Abhidhamma View:Productive and Supportive Kammas
[Presented by Dr.Tep Sastri @ SariputtaDhamma/JTN/Mult]
These two types of kamma help explain the Law of Kamma and give us an incentive to abandon unwholesome and develop only wholesome kamma.
CMA V, p. 201-202:
Productive(janaka) kamma is wholesome or unwholesome volition which produces resultant mental states and kamma-born materiality, both at the moment of rebirth-linking and during the course of existence. At the moment of conception, productive kamma generates the rebirth-linking consciousness and the kamma-born type of materiality constituting the physical body of the new being. During the course of existence, it produces other resultant cittas and the continuity of kamma-born materiality, such as the sense faculties, sexual determination, and the heart-base. Only a kamma that has attained the status of a full course of action can perform the function of producing rebirth-linking, but all wholesome and unwholesome kammas without exception can produce results during the course of existence.
Supportive kamma(upatthambaka) is kamma which does not gain an opportunity to produce its own result, but which, when some other kamma is exercising a productive function, supports it either by enabling it to produce its pleasant or painful results over an extended time without obstruction or by reinforcing the continuum of aggregates produced by another kamma. For example, when through the productive function of wholesome kamma one is reborn as human being, supportive kamma may contribute to the extension of one's life-span and ensure that one is healthy and well provided with the neccessities of life. When an unwholesome kamma has exercised its productive function by causing a painful disease, other kamma may support it by preventing medicines from working effectively, thereby prolonging the disease. When a being has been reborn as an animal through the productive force of unwholesome kamma, supportive kamma may facilitate the ripening of more unwholesome kamma productive of painful results, and may also lead to an extension of the life-span so that the continuity of unwholesome resultants will endure long.
