Under “What is a Khandha?”, point #2.2…
“We experience a rupa (sight, sound, smell, taste, touch, dhamma) with a citta AND based on that generate mental qualities of vedana, saññā, saṅkhāra, and viññāna. In each citta, the mind analyzes all these, and that citta is gone in a fraction of a second.”
Understand sōmanassa vēdanā and dōmanassa vēdanā are mental feelings. So, are they part of Vedanakkhandha?
