The "ego" like its correlative "non-ego", is the product of the body, mind etc. The only proof of the existence of the real Self is realisation.

There is no limit to the power of the human mind. The more concentrated it is, the more power is brought to bear on one point

Whatever you think, that you will be.

I am really not "cyclonic" at all. Far from it. What I want is not here, nor can I longer bear this "cyclonic" atmosphere. This is the way to perfection, to strive to be perfect, and to strive to make perfect a few men and women. My idea of doing good is this: to evolve out a few giants, and not to strew pearls before swine, and so lose time, health, and energy.

Our supreme duty is to advance toward freedom - physical, mental, and spiritual - and help others to do so.

The body and mind are continually changing, and are, in fact, only names of series of changeful phenomena, like rivers whose waters are in a constant state of flux, yet presenting the appearance of unbroken streams. Every particle in this body is continually changing; no one has the same body for many minutes together, and yet we think of it as the same body.

Stand in that reverent attitude to the whole universe, and then will come perfect non attachment.
