The following excerpt was taken from “The Summits of God-Life: Samadhi and Siddhi”
by Sri Chinmoy.

There is a great difference between seeing God and realising God. When we see God, we can see him as an individual or as an object or as something else. But we do not consciously and continuously embody Him and feel that He is our very own. When we see God, it is like seeing a tree. We do not at that time consciously embody the tree-consciousness. And since we do not embody it, we cannot reveal or manifest it. But when we realise something, at that time it becomes part and parcel of our life. We may see a flower, but only when we realise the flower do we actually become one with the consciousness of the flower.

When we merely see something, we cannot claim it as our very own, and that particular thing also will not claim us. Seeing is on the physical plane, while realising is on the inner plane. Seeing does not last, whereas realising does remain with us. If we see something, the vision may last for a short while; but when we realise something, this realisation lasts forever.
