The means whereby an embodied soul can become a pure or liberated soul.
The underlying principles upon which these theories are based are :
(1) the fact of the existence of soul, whose characteristic is knowledge (jiva);
(2) the fact of the existence of matter of any other real thing which has no consciousness (ajiva);
(3) impure souls draw matter towards themselves (asarva), and
(4) incorporate it with their own being (bandha); thus has the embodied state of the soul been perpetuated, death being followed by birth elsewhere in a material body. Now if this state of affairs is ever to cease,
(5) the influx of matter must be stopped (samvara) and
(6) the matter already in combination with the soul must be removed (nirjara). Then
(7) when this is accomplished the soul will live in everlasting enjoyment of all its own natural qualities (moksa).
