The Supreme Eternal is the only one who can offer liberation (salvation), and no one else. The Five (5) Forms of Release are:
1°) Impersonal liberation, which consists in blending into the radiance emanating from the supreme body of Krishna, God, the Supreme Person. The wise never accept this form of liberation.
2°) The one that allows us to live on the same planet as the Lord.
3°) She who gives the same bodily features as the Lord.
4°) The one that makes it possible to enjoy the same opulences as the Lord.
5°) The one that allows us to live in the company of the Lord.
Becoming conscious of Krishna, God, the Supreme Person, or spiritually enlightened, and engaging in his service of absolute love, these are the true signs of liberation.
Two weaknesses of heart are at the origin of man's loss.
During devotional service performed in the company of pure beings, fully absorbed in Krishna consciousness, certain elements must be completely overcome, especially our weaknesses of heart. The first, which leads to the first fall, is the desire to dominate material nature. It has the effect of leading the holy being to abandon the service of love and devotion offered to the Supreme Lord. And when this tendency to dominate material nature increases, then the second weakness manifests itself: the attachment to matter and the possession of matter. The problems of material existence come from these weaknesses of heart.
All beings must adopt Krishna consciousness, engage in devotional service, and thus acquire intelligence and become pure. Unless we come to that level where we know and understand Krishna and engage in the service of love and devotion to his Divine Person, we have not attained perfect intelligence, even though we would appear to the common people. The Lord indicates that it is very difficult to know Krishna until you are freed from all the consequences of your sins. To understand, one must first wash oneself of any defilement, of any guilty act. But the power and purity of the service of love and devotion are such that once one commits to it, one naturally reaches the level where one is freed from sin.
The service of love and devotion, in fact, is the Lord’s internal energy.
