Yoga is a generic name for any discipline by which one attempts to pass out of the limits of one's ordinary mental consciousness into a greater spiritual consciousness.

In order to explain why the ordinary Sadhus and Yogis take to tobacco and gānja [an intoxicant], I said that these cause stimulation of the physical brain. But these have reactions. And to stimulate the brain thus is not the proper process.

Safety lies in tending towards our highest and not in resting content with an inferior potentiality..... To rest in or follow after an inferior potentiality may seem safe, rational, comfortable, easy, but it ends badly, in some futility or in a mere circling down the abyss or in a stagnant morass. Our right and natural road is towards the summits.

When thou findest thyself scorning another, look then at thy own heart and laugh at thy folly.

The mind has these four levels: physical, vital, buddhi, higher mind. The Supermind is far above these.

That within us which seeks to know and to progress is not the mind but something behind it which makes use of it.

Can everybody contact the higher forces? No, not indeed; but they submit themselves to a discipline and this brings them success.
