Seeds in the a^laya consciousness which are already present at birth as the result of the activities of prior lifetimes. This term is commonly used in reference to the seeds which would determine one's spiritual proclivities， such as the distinction between potential for /sra^vaka， bodhisattva， etc. ［瑜伽论T 1579.30.478a］Also written 本有种子. These seeds are far more subtle than the seeds which are cultivated in the present lifetime 习成种姓.
