All the perquisites of manifest physical life are not applicable in the spiritual world. State of moksha salvation announces a soul atman liberating self from cycle of birth and death forever, rejoining its source Brahman, God Almighty. The question of soul having memories of reaching state of moksha just does not arise.
From the beginning of life every soul atman always acts as a Dhrishta, onlooker never interfering with creation of his. Although a soul atman manifest human body, it does not directly interfere in its life. All human beings have a free will exercising which they could discriminate right from wrong, truth from false.
The moment a soul atman reaches state of absolute purity it merges with God forever. Its independent identity though distinct remains as it is. Sri Ramakrishna Paramhansa and Maharshi Ramana exist no more yet any human being world over can call the spirit of Sri Ramakrishna Paramhansa or Maharshi Ramana on mother earth at will to seek their blessings.
So is the case with all enlightened souls right from stage of Mahavira, even Lord Krishna.
In the world of spirits, all liberated souls atmans were totally active. But from humanity point of view, they had no distinct role to play except we can seek their blessings in spirit form. For me it is a daily routine. I can talk to all these enlightened souls as if sitting across the table.
The stature of a soul is like an independent piece of a puzzle. Until it gains total purity it was outside the domain of God, bonded by present solar system. The moment a soul atman liberates it rejoins the puzzle and sets itself in its designated place.
The combined power of all souls’ atmans in cosmos in their pure form is what we called God Almighty in all its glory. Indulging in spirituality detailed in Bhagavad Gita we can understand the hidden underlying meaning of spiritual terminology.
On the physical plane all rivers finally joined the ocean losing their independent identity but in world of souls’ atmans the identity remains intact.
