I think chasing to reach the end is a bit pointless. I mean, why not just go with the waves? You'll end up drifting with a current, it's like trying to find the last wave. Being human we just need to accept this role. I think me saying this is too human. Emotions are instinctual to me. I think us wanting to find the end is human and in reality everything is just there.

what is meant by the end ?

Then end of knowledge is pure awareness it can only be reached by the pure of heart the flawless karma of a jnani cannot be understood until that state is reached yet even in total enlightenment one still exists therefore there is technically no end to knowledge or ones ability to grow into a higher potential state of consciousness .
