俱舍論疏 29.84

29.84

The treatise says, "Born in the form realm ... with the addition of the power of instruction," which explains that when in the form realm one generates higher dhyānas, it is through the power of cause, the power of karma, and the power of nature. If born in the desire realm, one generates higher formless [absorptions] through the power of cause, the power of karma, and the power of instruction. One generates form realm absorptions through the power of karma, the power of cause, the power of nature, and the power of instruction. Therefore it says, "in each case it should be understood that the power of instruction is added."
