Through selfless work, love of God grows in the heart. Then through his grace one realize him in course of time. God can be seen. One can talk to him as I am talking to you.
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.
As a boy holding to a post or a pillar whirls about it with headlong speed without any fear or falling, so perform your worldly duties, fixing your hold firmly upon God, and you will be free from danger.
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.
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.
As the shell, the pith and the kernel of the fruit are all produced form one parent seed of the tree, so from the one Lord is produced the whole of creation, animate and inanimate, spiritual and material.
When the head of a goat is severed from its body, the trunk struggles for some time, still showing signs of life. Similarly, though ahamkara (egotism) is slain in the perfect man, yet enough of its vitality is left to make him carry on the functions of physical life; but it is not sufficient to bind him again into the world.
One cannot attain divine knowledge till one gets rid of pride. Water does not stay on the top of a mound; but into low land it flows in torrents from all sides.
