“There are in the Upanishads, intimations of Krama-Mukti or the progressive process of the liberation of the soul.
The Upanishads are emphatic in their statements that one who reaches through unselfish meditation and knowledge this Supreme Cause does not return to the mortal coil, but proceeds further to the Absolute Reality.
The Mundaka Upanishad says that the sages in the world of Brahma are liberated beyond death in the end of time. Those who attain the world of the Karya-Brahman remain there until the end of the universe, enjoying the effects of their "Satyakamas" and "Satyasankalpas", the fruits of their desires and willings based on Truth. Whatever they wish arises then and there instantaneously, for they are in harmony with the Universal Being. They enjoy the highest approximation to the bliss of the Lord of the universe”.
This is what Bhattathri is highlighting in this Sloka 11.
