Purity
Purity or impurity depends upon the consciousness; in the divine consciousness everything is pure, in the ignorance everything is subject to impurity, not the body only or part of the body, but mind and vital and all. Only the self and the psychic being remain always pure.
Simplicity
As soon as all effort disappears from a manifestation, it becomes very simple, with the simplicity of a flower opening, manifesting its beauty and spreading its fragrance without clamour or vehement gesture. And in this simplicity lies the greatest power, the power which is least mixed and least gives rise to harmful reactions….
Humility
…. Humility is that state of consciousness in which, whatever the realisation, you know the infinite is still in front of you…. True humility consists in constantly referring oneself to the Lord, in placing all before Him. When I receive a blow (and there are quite a few of them in my sadhana), my immediate, spontaneous reaction, like a spring, is to throw myself before Him and to say, ‘Thou, Lord.’ Without this humility, I would never have been able to realize anything. And I say ‘I’ only to make myself understood, but in fact ‘I’ means the Lord through this body, his instrument. When you begin living THIS kind of humility, it means you are drawing nearer to the realization. It is the condition, the starting point.
Food
The first thing to be attained about eating, is to get rid of the greed of food, the attachment and desire,—to take it only as a need of the body, to think little of it and not to allow it to occupy a big place in the life; also to be satisfied with what you get, not to hanker. At the same time sufficient food should be taken, avoiding either deficiency or excess; an excessive coercion or nigraha in this respect (as opposed to reasonable control) often brings a reaction. One should go steadily, but not try to get too much done at once.
