As for being the formation branch: it is also only karma that brings about the general and the simultaneous. The Vijñaptimātratāsiddhi says: 'That which is initiated by that [ignorance] is precisely what is called the formation branch.' Hence, all karma experienced in the present life and specific karma that assists future karma are not the formation branch; only formations initiated by the aforementioned ignorance constitute formation. The matter of bodily and vocal karma is called designated form; relying on the active states and seeds of intention, mental karma is solely intention that constitutes the essence of the formation branch; the wholesome and unwholesome belonging solely to these five consciousnesses are not the formation branch, knowing clearly that they cannot bring about the general retribution.
