Vedanta is the last word in Vedic wisdom, and the author and knower of the Vedanta philosophy is Lord Krishna; and the highest Vedantist is the great soul who takes pleasure in chanting the holy name of the Lord. That is the ultimate purpose of all Vedic mysticism.
Sometimes river flows very strong, sometimes it flows very small, but it makes no difference to the ocean because it is satisfied in itself with its own quantity of water. Similarly, when our heart is cleansed with spirituality, we find pleasure and ecstasy with our own selves that is so sweet, so wonderful and so satisfying, that the so-called pleasures of this world no longer have any values, no appeal at all.
All our senses are imperfect. We claim to observe everything and anything, but we must admit that we can observe things under certain material conditions only, which are also beyond our control.
