2.75

Regarding 'Karmic fruition, going and returning between realms and stages, and subsequent arising would lack a cause': Chapter Three of the Mahāyānasaṃgraha says: 'If someone dies in this non-equipoised stage and takes birth, relying on the manas of the intermediate existence (antarābhava) state, defiled mental consciousness arises, linking rebirth in succession. This defiled mental consciousness ceases in the intermediate existence, and in the mother's womb, consciousness and the kalala blend with each other. If mental consciousness blends with that, once they have blended, relying on this consciousness, mental consciousness operates in the mother's womb. If so, then two mental consciousnesses should operate simultaneously in the mother's womb,' up to extensive explanations.
