The words, ’cause’ and ‘effect’ are only from a point of view. You say that this is the effect and that is the cause. In fact, the effect itself is the cause, being non-separate from the cause. Then again, which is cause and which is effect? When the pot is broken, it becomes clay. That means clay came from pot! This concept of cause and effect is purely a point of view. Our understanding that the cause came first and the effect came later is only a point of view. From the standpoint of Brahman, there is nothing that comes later, because Brahman itself is the effect. If at all the concept of ’cause’ and ‘effect’ is talked about, it is from the standpoint of the unmanifest and manifest conditions.
The unmanifest becomes manifest – that is called creation. Creation itself is not a proper word for us, because the word ‘creation’ is relevant only when something did not exist before, and later came into being. But it is not like that. That which is in an unmanifest, undifferentiated form, comes to be differentiated. One is in a subtle form, the other in a gross form. In a differentiated form it is called creation. In an undifferentiated form it is called dissolution. This creation is cyclic. The creation becomes unmanifest because it was manifest before. Unless it was manifest before, it cannot become unmanifest. We cannot talk about any sequence here.
