As the same sun appears as different when shining on different media, such as water and oil, so the same omnipresent Being, shining through different nervous systems, appears as different and forms the spirit, the subjective aspect of man's personality. When the nervous system is pure, Being reflects more and the spirit is more powerful, the mind more effective. When the nervous system is at its purest, then the Being reflects in all its fullness, and the inner individuality of the spirit gains the level of unlimited eternal Being. Thus it is clear that in its essential nature the spirit is undying and omnipresent. This explains the universality of individuality.

~ Maharishi Mahesh Yogi
[Commentary on Bhagavad Gita, Ch2, V17]

Finding the center of strength within ourselves is in the long run the best contribution we can make to our fellow men. ... One person with indigenous inner strength exercises a great calming effect on panic among people around him. This is what our society needs — not new ideas and inventions; important as these are, and not geniuses and supermen, but persons who can be, that is, persons who have a center of strength within themselves.

~ Rollo May

Now an extraordinary and helpful fact is that by
making Mind the object of our attention, not only does
the serenity which is its nature begin to well up of
its own accord but its steady unchanging character
itself helps spontaneously to repel all disturbing
thoughts.

~ Paul Brunton

[Notebooks Category 23: Advanced Contemplation > Chapter 7: Contemplative Stillness > # 10]

Acceptance of what is immediately frees you
from mind identification and thus reconnects
you with Being. Resistance is the mind.

~ Eckhart Tolle

Out of the intensity of the consciousness of the individuality, the

individuality itself seemed to dissolve and fade away into

boundless being; and this not a confused state, but the clearest of

the clear, the surest of the sure; utterly beyond words; where

death was an almost laughable impossibility, the loss of personality

(if so it were) seeming no extinction but the only true life.

~ Alfred Lord Tennyson

"There is nothing to practise. To know yourself, be yourself. To be
yourself, stop imagining yourself to be this or that. Just be. Let
your true nature emerge. Don't disturb your mind with seeking"
- Nisargadatta Maharaj
