You speak of doing good to the world. Is the world such a small thing? And who are you, pray, to do good to the world? First realise God, see Him by means of spiritual discipline. If He imparts power you can do good to others; otherwise not.
Right discrimination is of two kinds analytical and synthetical. The first leads one from the phenomena to the Absolute Brahman, while by the second one knows how the Absolute Brahman appears as the universe.
A devotee who can call on God while living a householder's life is a hero indeed. God thinks: 'He is blessed indeed who prays to me in the midst of his worldly duties. He is trying to find me, overcoming a great obstacle -- pushing away, as it were, a huge block of stone weighing a ton. Such a man is a real hero.
If you keep your heart immersed always in the depth of that holy love, your heart is sure to remain ever full to overflowing with the Divine fervour of sacred love.
Only two kinds of people can attain self-knowledge: those who are not encumbered at all with learning, that is to say, whose minds are not over-crowded with thoughts borrowed from others; and those who, after studying all the scriptures and sciences, have come to realise that they know nothing.
More are the names of God and infinite are the forms through which He may be approached. In whatever name and form you worship Him, through them you will realise Him.
How long do small girls play with their dolls? As long as they are not married and do not live with their husbands. After marriage they put the dolls away in a box. What further need is there of worshipping the image after the vision of God?
Live in the world like a waterfowl. The water clings to the bird, but the bird shakes it off. Live in the world like a mudfish. The fish lives in the mud, but its skin is always bright and shiny.
It is not lust alone that one should be afraid of in the life of the world. There is also anger. Anger arises when obstacles are placed in the way of desire.
The rishis of old attained the Knowledge of Brahman. One cannot have this so long as there is the slightest trace of worldliness. How hard the rishis laboured ! Early in the morning they would go away from the hermitage, and would spend the whole day in solitude, meditating on Brahman. At night they would return to the hermitage and eat a little fruit or roots. They kept their mind aloof from the objects of sight, hearing, touch, and other things of a worldly nature. Only thus did they realize Brahman as their own inner conciousness.
As for myself, I look upon all women as my Mother. This is a very pure attitude of mind. There is no risk or danger in it. To look upon a woman as one's sister is also not bad. But the other attitudes are very difficult and dangerous. It is almost impossible to keep to the purity of the ideal.
