________________ 6. Kusala-dharma-bija 113 here puts forth a bold and original solution to this problem. He says that we should distinguish between two kinds of kusala dharmas. There are some kusala dharmas which are innate, which do not presuppose any effort (ayatna-bhavi) but are always present in any given condition (upapatti-labhika). Then there are other kinds of kusala dharmas which are obtained only by effort or practice of meditations (prayogika). The for mer, i. e. the innate kusala dharmas are never completely annihilated. When a person on account of holding a grave mithyadoishti becomes samuchchhinna-kusala-mula, he destroys only his prayogika kusala-mulas. His innate kusala dharmas remain in the form of bijas intact in his santati from which arise new kusala dharmas in a favourable condition." The statement of the Kosakara that even a samuchchhinnakusala-mula possesses a subtle element of kusala is not free from contradiction. The Bhashya does not contain any criticism of this incompatible position. Even Yasomitra who defends the theory of bija against a criticism from Samghabhadra is silent on this contradictory statement of the Kosakara. Fortunately, a brief criticism of this major controversy has survived in our Vtitti, The Dipakara gives the meaning of the term samuchchhinna-kusala-mula as understood in the Vaibhashika tradition, and criticises the theory of bija as propounded by the Kosakara. .. According to the Vaibhashikas, the mithya-d'ishti and the kusala-mulas each consists of three basic grades, viz., mridu (subtle or slight), madhya (of medium nature) and adhimatra (extreme). Each of these three grades is further divided into these three, e. g. mridu-msidu........adhimatra-adhimatra. The kusala-mulas pertaining to the arupavachara and the rupavachara are destroyed by the maidu and madhya mithyadrishtis.* The adhimatra mithya-drishti destroys the prayogika kusala-mulas pertaining to the kama world, leaving in such a 1 Saku. p. 147.
