If you desire to be pure, have firm faith, and slowly go on with your devotional practices without wasting your energy in useless scriptural discussions and arguments. Your little brain will otherwise be muddled.
When an unbaked pot is broken, the potter can use the mud to make a new one; but when a baked one is broken, he cannot do the same any longer. So when a person dies in a state of ignorance, he is born again; but when he becomes well baked in the fire of true knowledge and dies a perfect man, he is not born again.
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.
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.
One should not think, 'My religion alone is the right path and other religions are false.' God can be realized by means of all paths. It is enough to have sincere yearning for God. Infinite are the paths and infinite are the opinions.
A bath in Ganges undoubtedly absolves one of all sins; but what does that avail? They say that the sins perch on trees along the banks of the Ganges. No sooner does the man come back from the holy waters that the old sins jump on his shoulders from the trees. The same old sins take possession of him again. He is hardly out of the waters before they fall upon him.
