The Fifth Karma Granth
It is said that when pure emotions arise, the soul ascends from the state of being bound to the state of liberation. And as it ascends through the stages of purification, it descends through the same number of stages of defilement when it falls back. Thus, there are as many stages of defilement as there are stages of purification. However, when considering the perspective of the क्षपक श्रेणि (Kshapaka Shreni), the stages of purification are more numerous than the stages of entry. Because the soul, which is ascending through the stages of purification, does not descend below those stages. If there were an equal number of stages of defilement as stages of purification, then the soul would inevitably fall back in the same way as it does in the उपशम श्रेणि (Upshama Shreni). But this does not happen. Once the soul ascends through the क्षपक श्रेणि (Kshapaka Shreni), it does not descend. This implies that the number of stages of purification is greater than the number of stages of defilement in the क्षपक श्रेणि (Kshapaka Shreni).
While there are stages of purification, only the four-fold bond of auspicious natures occurs. And when there are extreme stages of defilement, there is no bond of auspicious natures at all. Some beings, at the time of extreme defilement, bind auspicious natures like the body of a hell-bound being, etc. But due to their nature of existence, they only have a two-fold bond at that time. And even those auspicious natures that bind with medium results have a two-fold bond. Therefore, there is never a one-fold bond of auspicious natures.
In this way, by explaining the stages of the bond of the parts, their causes, the stages of karma, and how many natures have a four-fold bond, etc., the special nature of auspicious and inauspicious karma is explained.
"The subtle, natural, three-part, four-fold bond is acquired. The bond of the body is inauspicious, while the bond of the mind is auspicious." (15)
