Advaita is the only system that gives us complete control over ourselves, takes off all dependence and its associated superstitions, thus making us brave to suffer, brave to do, and in the long run, attain to absolute freedom.
There is only one sin and it is: weakness. When I was a boy, I read Milton's Paradise Lost. The only good man I had any respect for was Satan. The only saint is that person who never weakens, faces everything, and determines die game.
There can be no love so long as there is lust- even a speck of it, as it were, in the heart. None but men of great renunciation, none but mighty giants among men, have a right to that Love Divine. If that highest ideal of love is held out to the masses, it will indirectly tend to stimulate its worldly which dominates the heart of man- for, meditating on love to God by thinking of oneself as His wife or beloved, one would very likely be thinking most of the time of one's own wife- the result is too obvious to point out.
There may be a million microbes of misery floating about us. Never mind! They dare not approach us, they have no power to get a hold on us, until the mind is weakened.
Wherever there is evil and wherever there is ignorance and want of knowledge, I have found out by experience that all evil comes, as our scriptures say, relying upon differences, and that all good comes from faith in equality, in the underlying sameness and oneness of things. This is the great Vedantic ideal.
Some people are so afraid of losing their individuality. Wouldn't it be better for the pig to lose his pig-individuality if he can become God? Yes. But the poor pig does not think so at the time. Which state is my individuality? When I was a baby sprawling on the floor trying to swallow my thumb? Was that the individuality I should be sorry to lose? Fifty years hence I shall look upon this present state and laugh, just as I now look upon the baby state. Which of these individualities shall I keep?
When we come to nonattachment, then we can understand the marvelous mystery of the universe: how it is intense activity and at the same time intense peace, how it is work every moment and rest every moment.
Just as the law of gravitation existed before its discovery and would exist if all humanity forgets it, so it is with the laws that govern the spiritual world. The moral, ethical and spiritual relations between soul and soul and between individual spirits and the Father of all spirits were there before their discovery and would remain even if we forget them.
Hold to the idea, "I am not the mind, I see that I am thinking, I am watching my mind act," and each day the identification of yourself with thoughts and feelings will grow less, until at last you can entirely separate yourself from the mind and actually know it to be apart from yourself.
All action of Sattva, a modification of Prakriti characterised by light and happiness, is for the soul. When Sattva is free from egoism and illuminated with the pure intelligence of Purusha, it is called the self-centred one, because in that state it becomes independent of all relations.
