Hello JKSCJ,
You wrote, “From what I understand, no part of the panchakhanda carries forward at the end of a particular bhava.”
Why (or how) did you come to that understanding? That is the critical question.
There are 11 types of rupa included in rupakkhandha, as pointed out in #7 of “Difference Between Physical Rūpa and Rūpakkhandha.”
- The same applies to the other four “khandhas” of vēdanākkhandha, saññākkhandha, saṅkhārakkhandha, and viññānakkhandha.
- The records of the five khandhas are preserved as “namagotta.” Of course, we cannot recall most of them, even within our lives. But those with iddhi powers (even some anariya yogis) can recall their past lives. A Buddha can recall as far as he wishes.
