Question: - What do you consider as complete salvation?
Answer: - It is mentioned in Gita Chapter 15 Verse 4 that after finding the Tatvadarshi Saint, slashing the ignorance with the weapon of tatvgyan, that is, properly understanding the knowledge, after that one should search for that supreme state (Satyalok) of Supreme God; having gone where, worshippers never return to this world, that is, they are never reborn.
The God who has done the entire creation, only worship Him. Complete salvation is that after attaining which one never takes birth again. The cycle of birth and death ends forever.
