According to Milyin, the idea of the world being an illusion, or Maya, in Hinduism, resonates with the findings of quantum mechanics. Quantum mechanics is a fundamental theory in physics that describes the behavior of nature at the scale of atoms and subatomic particles. 

Some say that Lord Krishna’s insights on the battlefield in the Mahabharata resonate with the principles of quantum reality. For example, in the Bhagavad Gita, Krishna explained to Arjuna that there are many powerful creators and many more universes than this universe. He also offered Arjuna a glimpse of multiple cosmic creations and annihilations. 

Krishna is the Hindu god of compassion, protection, and love. He is an important character in many Hindu sacred texts. According to Puranic sources, Krishna’s disappearance marks the end of Dvapara Yuga and the start of Kali Yuga, which is dated to 17/18 February 3102 BCE.

Multiverse. The idea of parallel universes disturbs many scientists, but is entirely natural in Indian traditions. In the Bhagavad Gita, Lord Krishna offers a glimpse of multiple cosmic creations and annihilations to his disciple Arjun; different universes are located in different parts of the cosmic body of Krishna.

In the Bhagavad Gita, Krishna explains that different universes are located in different parts of his cosmic body. He also says that everything happens for a good reason. 

According to Hinduism, every universe is covered by seven layers, each ten times greater than the previous one. These layers are: 

Earth, Water, Fire, Air, Sky, The total, Energy, False ego. 

Hinduism says that there are innumerable universes, and although they are unlimitedly large, they move about like atoms.

Lord Krishna showed the Universal Form ( Vishwaroopa ) because He indeed is the Whole Unified Universe , the Supreme Being . The Supreme Being , though unborn and eternal manifests Himself in human form to overthrow the forces of ‘ avidya’

In the Bhagavad Gita, Krishna showed his universal form, also known as Vishwaroopa, for a few reasons: 

• To avoid war: Krishna wanted to warn Duryodhana and his supporters of the might of the opposing side. 
• To inspire devotion: Krishna wanted to inspire people to devote themselves to him. 
• To curb pride: Krishna showed the universal form to curb pride. 
• To reveal the secret of Godhood: Krishna wanted to reveal that God is in everyone and in the whole universe. 
• To draw attention: Krishna wanted to draw the attention of those who have no love for God. 

The universal form has thousands of heads and hands. It’s not God’s original form.

In the Bhagavad-gita Arjuna asks Krishna to show him His universal form. Why does Arjuna want to see it? Because he desires to have visual confirmation of Krishna’s previous verbal declaration “I sustain the whole universe with just a fragment of Myself

In the Bhagavad Gita, Arjuna asks Krishna to show him his universal form for a few reasons: 

• Visual confirmation Arjuna wants to see visual confirmation of Krishna’s statement that he sustains the universe with a fragment of himself. 
• To convince others Arjuna wants to see Krishna’s universal form to convince others who may think Krishna is an ordinary person. 
• To set a criterion Arjuna wants to set a criterion for the future, when there may be imposters who pose as incarnations of God. 
• For the benefit of others Arjuna wants to see the universal form for the benefit of others who may doubt that Krishna is God. 

Arjuna sees Krishna’s universal form, which has unlimited eyes, mouths, arms, faces, and stomachs. The form is decorated with celestial ornaments, garlands, garments, and divine scents. Arjuna also sees Krishna wearing many divine upraised weapons.

In the Bhagavad Gita, Krishna tells Brahma that he is the creator of this universe. Krishna also tells Brahma that there are many other universes, each with their own creator and birth and death cycle

Krishna also explains to his disciple Arjun that there are many cosmic creations and annihilations. Different universes are located in different parts of Krishna’s cosmic body. 

The Hindu multiverse has several Lokas, each corresponding to different levels of consciousness and spiritual evolution. The concept of the Loka illustrates Hinduism’s embrace of diversity within the multiverse

The idea of the illusion of reality is that our sensory perception limits our everyday experience of reality. We perceive the world through a veil of illusions created by our minds. This means that we don’t experience reality as it is, but only as we perceive it.

The illusion comes when we confuse the reality we experience with the physical reality. The Vedantic philosophers of ancient India spoke of this confusion as maya. 

Some examples of illusions include: 

• Rabbit-duck illusion: This ambiguous figure can be seen as either animal. 
• Relative shape or size: A circle might seem smaller or larger depending upon what is around it. 

There is also a book called The Illusion of Reality by Howard L. Resnikoff. It is intended as a text for an advanced undergraduate or a graduate introduction to information science

The multiverse is a hypothetical set of all universes. It is thought to include everything that exists, such as space, time, matter, energy, information, and the physical laws and constants that describe them

The idea of multiple cosmic creations can be found in Hindu mythology. In the Bhagavad Gita, Lord Krishna tells his disciple Arjun about multiple cosmic creations and annihilations.  Krishna explains that there are many powerful creators and many more universes than this one.  He also says that different universes are located in different parts of his cosmic body. 

The multiverse theory was first proposed by Indian astronomer Brahmagupta in the 6th century AD. Brahmagupta’s theory stated that the universe is made up of an infinite number of tiny universes, each with its own set of physical laws. 

Hugh Everett, a PhD student at Princeton in 1955, introduced the idea of the universe “splitting” into different versions of itself when faced with quantum choices

In the Bhagavad Gita, Krishna grants Arjuna the ability to see his infinite form, or viśhwarūp. This form is considered the supreme form of Vishnu, and contains the entire universe. Arjuna sees Krishna with unlimited faces, eyes, arms, and stomachs. He is also decorated with celestial ornaments and wields many divine weapons

The viśhwarūp vision is revealed to Arjuna before the Mahabharata war. Some elements of the vision can be traced back to ancient Indian concepts of integration and disintegration

Lord Krishna is considered infinite, eternal, and unchangeable. He is also said to be without a beginning or end, and his power has no limits. Krishna is said to pervade everywhere, including all atoms, space, time, and spirit souls. He is also said to have perfect control of his creation

Krishna is considered the ultimate source from which Brahma, Vishnu, Shiva, and Prakriti originate. He is also said to have had infinite avatars

According to Hinduism Stack Exchange, Lord Krishna lives in the tenth dimension. The fifth sub-level of the tenth dimension is Goloka Dham, where Krishna resides. Goloka Dham is considered the highest spiritual abode in the spiritual world. 

Quantum mechanics and the Mahabharata have some parallels: 

• Maya: The word “Maya” has the same meaning in both Vedanta and quantum physics, which is “ultimate reality”. The elusive nature of reality in quantum mechanics mirrors the enigmatic concept of Maya in Hindu philosophy. 
• Unity: Vedic Mechanics and quantum mechanics both focus on the concept of unity. In Vedic Mechanics, everything in the universe is seen as interconnected and interdependent. 
• Observer and observed: Quantum physics eliminates the gap between the observer and the observed. The Upanishads say that the observer and the observed are the same things. 
• Duty: The Mahabharata teaches the valuable lesson of duty. 
• Faith in God: The Mahabharata shows deep faith in God. 

Some other parallels between Vedanta and quantum mechanics include: 

• The concept that the Universal observer, or awareness, is what causes things to come into existence

Vedanta is a Vedic belief that focuses on understanding the universe within. Vedanta and quantum physics both say that the world is an illusion. Vedanta says that consciousness is the only thing that is real and that it is the fundamental principle from which the universe emerged.  Vedanta also says that the mind is made of waves, or vrittis, and that these waves become the objects that we see in the physical universe. 

Advaita Vedanta claims that there is only one substance that is the origin of the universe. This substance is independent of time and space

Quantum consciousness is a group of hypotheses that suggest that consciousness cannot be explained by classical mechanics or connections between neurons. Instead, it’s caused by quantum-mechanical phenomena like entanglement and superposition. 

There are three main approaches to consciousness in quantum physics: 

• Consciousness is a result of quantum processes in the brain. 
• Quantum concepts can be used to understand consciousness without referring to brain activity. 
• Matter and consciousness are two aspects of one underlying reality. 

One theory of consciousness is that superpositions of quantum states in the brain collapse when observed or when a conscious decision is made. This collapse results in a specific outcome or decision. 

Another theory is that consciousness is made up of unobservable quantum information built into quantum brain states.

The ancient Hindu scripture, Bhagavad Gita, has provided quantum scientists with insights into the universe’s complexities. The Bhagavad Gita emphasizes the interconnectedness of all things, which Einstein believed was central to his scientific work. The Bhagavad Gita also provides a framework for understanding the nature of the observer and their interaction with matter.

Here are some other reasons why quantum scientists may love the Bhagavad Gita: 

• Interconnectedness: The Bhagavad Gita teaches that all beings are intrinsically linked. 
• Observer: The Bhagavad Gita provides a framework for understanding the nature of the observer. 
• Energy: The Bhagavad Gita states that energy can be neither created nor destroyed, but can change form. This is known as the Law of Conservation of Energy

Some other famous physicists who were influenced by Hindu dharma include

• Carl Sagan American astronomer, cosmologist, astrophysicist, astrobiologist, and philosopher 

• Werner Heisenberg Created quantum mechanics in the 1920s 
• Niels Bohr Created quantum mechanics in the 1920s
