俱舍論疏 3.149

3.149

論「豈有二形至二形化生」，釋通妨也。准此，善趣無有二形化生。此上所說唯異熟根。若兼染污，竝加意、捨。

The commentary states: "Could there be two forms [...] apparitional birth with two forms?" This resolves an objection. According to this, in the good destinies there is no apparitional birth with two forms. What has been discussed above refers only to maturation faculties. If defiled ones are also included, mind and equanimity are both added.
