God is Undivided and Indivisible

Sage Vasishtha 

The LORD (Shiva) said:

The worship of that Lord is true worship and by that worship one attains everything. He is undivided and indivisible, non-dual and not fashioned or created by activity; he is not attained by external efforts. His adoration is the fountain-source of joy.

The external worship of a form is prescribed only for those whose intelligence has not been awakened and who are immature like little boys. When one does not have self-control, etc., he uses flowers in worship; such worship is futile, even as adoring the self in an external form is futile. However, these immature devotees derive satisfaction by worshipping an object created by themselves; they may even earn worthless rewards from such worship.

I shall now describe to you the mode of worship appropriate to enlightened people like you. The Lord fit to be worshipped is indeed the one who upholds the entire creation, who is beyond thought and description, who is beyond the concepts of even the 'all' and the 'collective totality'. He alone is referred to as 'God' who is undivided and indivisible by space and time, whose light illumines all the objects, who is pure and absolute consciousness. He is that intelligence which is beyond all its parts, which is hidden in all that is, which is the being in all that is and which robs all that is of their being (i.e., which veils the truth). This Brahman is in the middle of being and non-being, it is God, and the truth that is indicated as 'OM'. It exists everywhere like the essence in a plant. That pure consciousness which is in you, in me and in all the gods and goddesses alone is God. Holy one, even the other gods endowed with form are indeed nothing but that pure consciousness. The entire universe is pure consciousness. That is God, that 'all' I am; everything is attained from and through him.

That God is not distinct from anyone, O Holy one, nor is he difficult to attain: he is for ever seated in the body and he is everywhere like space. He does everything,  he eats, he holds everything together, he goes, he breathes, he knows every limb of the body. He is the light in which all these limbs function and all the diverse activities take place. He dwells in the cave of one's own heart. He transcends the mind and the five senses of cognition; therefore he cannot be comprehended nor described by them - yet for the purpose of instruction, he is indicated as 'consciousness'. Hence, though it appears as though he does everything, he does nothing. That consciousness is pure and seemingly engages itself in the activities of the world to the same extent as the spring does in the flowering of trees.
