This vast cosmos with all its contents (atom, molecule, sun, moon, planet, and star) all are created out of single stuff. That single stuff is consciousness.+

The sky, the stars, planets, the sun, the moon, the earth, the mountains, the oceans, and people are all an illusion created out of the Soul, which is present in the form of consciousness, but consciousness is not specifically any of these while simultaneously being all of these.

Only when the Soul is hidden within the illusory form, time, and space the sky, the star, planet, the sun, the moon, the earth, the mountain, the ocean, and the persons are a reality.

The nature of the Soul is the formless, timeless, and spaceless existence.

Thus, it is necessary to realize the sky, the star, planet, the sun, the moon, the earth, the mountain, the ocean, and the persons are all created out single stuff, which is consciousness.

Consciousness is the ultimate truth or Brahman or God in truth. Thus, God alone is real, the sky, the star, planet, the sun, the moon, the earth, the mountain, the ocean, and the person are all merely an illusion created out of consciousness.

Remember:~

This vast cosmos with all its contents (atom, molecule, sun, moon, planet, and star) all are created out of single stuff. That single stuff is the Soul, which is present in the form of consciousness.

Knowledge of the single stuff is Self-knowledge or Brahma Gnana or Atma Gnana.

The Soul is the Self. the Soul is present in the form of consciousness. The awareness is the nature of the Soul or consciousness. Consciousness is existence itself.

The consciousness is ever-present. Without consciousness, the world, in which you exist ceases to exist. The consciousness is Self-evident. It is not established by extraneous proofs. It is not possible to deny consciousness because it is the very essence of the one who denies it. Consciousness is the basis of all kinds of knowledge, presuppositions, and proofs. Consciousness is everything. Thus, consciousness is the ultimate truth or Brahman or God in truth.

Remember:~

People think everything is energy but without consciousness, how can one know it is energy. It is only intellectual speculation.

Chandogya Upanishad:~ One who meditates upon and realizes the 'Self' discovers that everything in the cosmos-- energy and space, fire and water, name and form, birth and death, mind and will, word and deed, mantrams and meditation--all come from the Self.

Remember:~

The sun, the moon, the stars, planets shine because of the Soul or Spirit. The Soul shines and all things else shine as a result. Everything in the universe reflects but that light of the Soul which is present in the form of consciousness. Merely knowing the truth is not enough to escape from the tangle of illusion.

The mind is in the form of the universe. From the standpoint of the Soul the innermost Self the universe is merely an illusion. The illusion arises from ignorance. Enlightenment comes with detachment from the illusion by realizing the experience of the form, time and space are one in essence.

Bhagavad Gita: ~ Brahmano hi pratisthaham ~ Brahman (God) is considered the all-pervading consciousness, which is the basis of all the animate and inanimate entities and material. (14.27).

When Bhagavad Gita says, God is considered the all-pervading consciousness which is the basis of all the animate and inanimate entities and material then everything is nothing but the consciousness.

The Soul, the Self, which is present in the form of consciousness, is the substance of the dualistic illusion because the dualistic illusion is created out of the consciousness.:~Santthosh Kumaar
