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.

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.

The winds of grace blow all the time. All we need to do is set our sails.

All will surely realize God. All will be liberated. It may be that some get their meal in the morning, some at noon, and some in the evening; but none will go without food. All, without any exception, will certainly know their real Self.

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.

Whoever wants God intensely, finds Him. Go and verify it in your own life.

Unless one always speaks the truth, one cannot find God Who is the soul of truth.
