成唯識論演祕 4.40

4.40

而壽不滅亦不離煖。此是同法，舉此為喻而例識體在定令有，心行等者文同來爾。

Vitality is not destroyed, nor does it depart from warmth. This is an analogous dharma. Adducing this as an example, one analogously requires that the consciousness-substance be present during absorption. The passage on citta-saṃskāra and so forth likewise applies to this.
