We have seen that the karmāśaya has three fructifications, viz. jāti, āyush and bhoga. Now generally the karmāśaya is regarded as ekabhavika or unigenital, i.e. it accumulates in one life. Ekabhava means one life and ekabhavika means the product of one life, or accumulated in one life. Regarded from this point of view, it may be contrasted with the vāsanās which remain accumulated from thousands of previous lives since eternity, the mind, being pervaded all over with them, as a fishing-net is covered all over with knots. This vāsanā results from memory of the experiences of a life generated by the fructification of the karmāśaya and kept in the citta in the form of potency or impressions (saṃskāra). Now we have previously seen that the citta remains constant in all the births and rebirths that an individual has undergone from eternity; it therefore keeps the memory of those various experiences of thousands of lives in the form of saṃskāra or potency and is therefore compared with a fishing-net pervaded all over with knots. The vāsanās therefore are not the results of the accumulation of experiences or their memory in one life but in many lives, and are therefore called anekabhavika as contrasted with the karmāśaya representing virtuous and vicious actions which are accumulated in one life and which produce another life, its experiences and its life-duration as a result of fructification (vipāka). This vāsanā is the cause of the instinctive tendencies, or habits of deriving pleasures and pains peculiar to different animal lives. Thus the habits of a dog-life and its peculiar modes of taking its experiences and of deriving pleasures and pains are very different in nature from those of a man-life; they must therefore be explained on the basis of an incipient memory in the form of potency, or impressions (saṃskāra) of the experiences that an individual must have undergone in a previous dog-life. Now when by the fructification of the karmāśaya a dog-life is settled for a person, his corresponding vāsanās of a previous dog-life are at once revived and he begins to take interest in his dog-life in the manner of a dog; the same principle applies to the virtue of individuals as men or as gods (IV. 8). If there was not this law of vāsanās, then any vāsanā would be revived in any life, and with the manifestation of the vāsanā of animal life a man would take interest in eating grass and derive pleasure from it. Thus Nāgeśa says: “Now if those karmas which produce a man-life should manifest the vāsanās of animal lives, then one might be inclined to eat grass as a man, and it is therefore said that only the vāsanās corresponding to the karmas are revived.”
