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.
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.
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.'
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.
I have now come to a stage of realization in which I see that God is walking in every human form and manifesting Himself alike through the sage and the sinner, the virtuous and the vicious. Therefore when I meet different people I say to myself, “God in the form of the saint, God in the form of the sinner, God in the form of the righteous, God in the form of the unrighteous.
The truth is that you cannot attain God if you have even a trace of desire. Subtle is the way of dharma. If you are trying to thread a needle, you will not succeed if the thread has even a slight fiber sticking out.
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.
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.
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.
Wisdom leads to unity, but ignorance to separation.
So long as God seems to be outside and far away, there is ignorance.
But when God is realised within, that is true knowledge.
