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.
Little children play with dolls in the outer room just as they like, without any care of fear or restraint; but as soon as their mother comes in, they throw aside their dolls and run to her crying, "Mamma, mamma." You too, are now playing in this material world, infatuated with the dolls of wealth, honour, fame, etc., If however, you once see your Divine Mother, you will not afterwards find pleasure in all these. Throwing them all aside, you will run to her.
What Brahman is cannot be described. All things in the world — the Vedas, the Puranas, the Tantras, the six systems of philosophy — have been defiled, like food that has been touched by the tongue, for they have been read or uttered by the tongue. Only one thing has not been defiled in this way, and that is Brahman. No one has ever been able to say what Brahman is.
So long as one does not become simple like a child, one does not get divine illumination. Forget all the worldly knowledge that thou hast acquired and become as a child, and then will thou get the divine wisdom.
Spirituality automatically leads to humility. When a flower develops into a fruit, the petals drop off on its own. When one becomes spiritual, the ego vanishes gradually on its own. A tree laden with fruits always bends low. Humility is a sign of greatness.
The sun can give heat and light to the whole world, but he cannot do so when the clouds shut out his rays. Similarly as long as egotism veils the heart, God cannot shine upon it.
Travel in all the four quarters of the earth, you will find nothing (no true religion) anywhere. Whatever there is, is only here (i .e . in one 's own heart.)
It's enough to have faith in one aspect of God. You have faith in God without form. That is very good. But never get into your head that your faith alone is true and every other is false. Know for certain that God without form is real and that God with form is also real. Then hold fast to whichever faith appeals to you.
Sunlight is one and the same wherever it falls; but only a bright surface like that of water, or of a mirror reflects it fully. So is the light Divine. It falls equally and impartially on all hearts, but the pure and pious hearts of holy men receive and reflect that light well.
The ordinary man says in his ignorance, "My religion is the sole religion, my religion is the best." But when his heart is illuminated by the true knowledge, he knows that beyond all the battles of sects and of sectaries presides the one, indivisible, eternal and omnipresent Benediction.
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.
