Adi Shankara

Though one lives in the conditionings, they, the contemplative one, remain ever unconcerned with anything, or they may move about like the wind, perfectly unattached.

On the destruction of the conditionings, the contemplative one is totally absorbed in Vishnu, the all-pervading spirit.

Like water into water, space into space, and light into light.

Realize that, to be Brahman, the attainment of which leaves nothing more to be attained, the blessedness of which leaves no other blessing to be desired, and the knowledge of which leaves nothing more to be known.

Realize that to be Brahman, which when seen leaves nothing more to be seen, which having become one is not born again in this world, and which, when knowing, leaves nothing else to be known.

Realize that to be Brahman, which is existence, knowledge, bliss, absolute.

Which is non-dual, infinite, eternal, and one.

Realize that to be Brahman, which is non-dual, indivisible, one and blissful, and which is indicated in Vedanta as the immutable substratum.

Deities like Brahma and others taste only a particle of the unlimited bliss of Brahman and enjoy in proportion their share of that particle.

All objects are pervaded by Brahman.

All actions are possible because of Brahman.

Therefore Brahman permeates everything as butter permeates milk.

Realize that to be Brahman, which is neither subtle nor gross, neither short nor long, without birth or change, without form, qualities, color and name.

that by the light of which the luminous orbs like the sun and moon are illuminated, but which is not illumined by their light, realize that to be Brahman.

Pervading the entire universe outwardly and inwardly, the Supreme Brahman shines of itself, like the fire that permeates a red-hot iron ball and glows by itself.

There exists nothing that is not Brahman.

If any object other than Brahman appears to exist, it is unreal, like the mirage.

Attaining the knowledge of the reality, one sees the universe as the non-dual Brahman.

Though Atman is pure consciousness and ever-present everywhere, yet it is perceived by the eye of wisdom alone.

The jiva, free from impurities, being heated in the fire of knowledge, kindled by hearing, and so on, shines of itself like gold.
