Various schools of Buddhist thought held that karmic effects arose out of seeds that were latent in an individual's
mindstream or psycho-physical continuum. Rupert Gethin describes the theory thus: When I perform an action motivated by greed, it plants a 'seed' in the series of
dharmas [phenomena] that is my mind. Such a seed is not a thing in itself - a dharma but merely the modification or 'perfuming' of the subsequent flow of dharmas consequent upon the action. In the course of time this modification matures and issues in a particular result, in the same way as a seed does not produce its fruit immediately, but only after the 'modifications' of the shoot, stem, leaf, and flower. The
Sautrantika school held such a theory as did the
Mahasamghikas and the early Mahasisakas. The Sautrantika Sthavira Srilata held a conception of "subsidiary element" (
anudhatu or *
purvanudhatu) which also corresponds to this theory of seeds. In the Bashyam Vasubandhu connects the Sautrantika theory of seeds with the notion of the latent defilements or
anusaya: The Sautrantikas define
anusayas as
kleshas in the state of seeds and say that they are not separate
dravyas (substances). Anusayas are dormant, i.e., not actualized, while paryavasthanas (active defilements) are awakened. Likewise, the
Nyayanusara of Sanghabhadra states that the theory had different terms to refer to "seeds": There are certain masters who give different names to these seeds, each according to his own understanding. Some call them subsidiary elements (
anudhatu), others call them impressions (
vasana); still others call them capability (
samarthya), non-disappearance (
avipranasa), or accumulation (
upacaya). The theory is considerably extended in the
Consciousness-only teachings of the
Yogacara school of Buddhism. According to this theory, all experiences and actions produce
bīja as impressions, stored in the
alaya (storehouse) consciousness. The external world is produced when the seeds "perfume" this consciousness. ==As mantras==
