The ever liberated and liberated souls are always enjoying the supreme Lord Sriman Narayana in Sri Vaikundam. Although the souls living in this world are also eligible to have this enjoyment, they due to their sinful deeds, are unable to have such an experience; as a result, they live in this world. The Lord, with a view to correct the denizens of this world and receive their services, has out of compassion, manifested himself as Sri Rama and Sri Krishna.
