Men bound hand and foot in the endless chain of cause & effect cannot free each other.

Different people call on [God] by different names: some as Allah, some as God, and others as Krishna, Siva, and Brahman. It is like the water in a lake. Some drink it at one place and call it 'jal', others at another place and call it 'pani', and still others at a third place and call it 'water'. The Hindus call it 'jal', the Christians 'water', and the Moslems 'pani'. But it is one and the same thing.

As for me, I consider myself as a speck of the dust of the devotee's feet.

All troubles come to an end when the ego dies

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.

Work, apart from devotion or love of God, is helpless and cannot stand alone.

The ego is like the root of a banyan tree, you think you have removed it all then one fine morning you see a sprout flourishing again.
