The meaning of realization is knowing the truth as it is and remove all the illusions. In philosophy the word realization is used in many contexts. But mainly it is known as self realization. Knowing the self is greatest among all knowledge. At the realization one does not grieve as ignorance is got rid off by meditation upon the self. The realized self does not grieve because he experiences the Self as the self-same and all pervading. It dwells in the hearts of all without any physical attachment and is without any name or form. The wise realizes then truth that the self is distinct from the sense organs.
