In Indian Logic (Nyāya), non-existence is called abhāva. There are various divisions and subdivisions of non-existence. Mutual non-existence” means non-existence due to being different. For instance, a table is different from a chair. In a table, a chair does not exist. This is true for all three phases of time.
Based on Śrīla Jīva Gosvāmī’s Bhagavat Sandarbha. By Satyanarayana Dasa. The Lord has two types of energy: parā and aparā. Parā means distant, beyond, superior, and so on. The energy is called parā because it is superior to, or beyond, the material energy, which is thus called aparā, i.e. near or inferior. In the Bhagavad Gītā, Kṛṣṇa states that the living beings can be counted as parā, because of their conscious nature:
By Satyanarayana Dasa: Among modern spiritualists there is a common belief that each individual being is full of bliss and knowledge. They claim that everyone is perfect, and it is just a matter of discovering one’s real nature. The Self is part of God, as confirmed by Sri Krsna, “The living being in this world is My eternal fragment” (Bhagavad Gita 15.7).
