Imagine a limitless expanse of water: above and below, before and behind, right and left, everywhere there is water. In that water is placed a jar filled with water. There is water inside the jar and water outside, but the jar is still there. The 'I' is the jar.
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.
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.
Bhakti is the one essential thing.
To be sure, God exists in all beings.
Who, then is a devotee? He whose mind dwells on God.
But this is not possible as long as one has egotism and vanity.
The water of God's grace cannot collect
on the high mound of egotism. It runs down.
It is true that God is even in the tiger, but we must not go and face the animal. So it is true that God dwells even in the most wicked, but it is not meet that we should associate with the wicked.
God laughs on two occasions. He laughs when the physician says to the patient's mother, 'Don't be afraid, mother; I shall certainly cure your boy.' God laughs, saying to Himself, 'I am going to take his life, and this man says he will save it!' The physician thinks he is the master, forgetting that God is the Master. God laughs again when two brothers divide their land with a string, saying to each other, 'This side is mine and that side is yours.' He laughs and says to Himself, 'The whole universe belongs to Me, but they say they own this portion or that portion.'
The magnetic needle always points to the north, and hence it is that sailing vessel does not lose her direction. So long as the heart of man is directed towards God, he cannot be lost in the ocean of worldliness.
