Yes. The post, “Kāma Guṇa – Origin of Attachment (Tanhā)” is good to read.
All vedana, including Sāmisa vēdanā, “samphassa-jā-vēdanā,” and nirāmisa vēdanā are included in the five types of vedana (sukha, dukkha, somanassa, domanassa, upekkha or neutral.)
It is good to understand how each of those different categories can arise.
Another important thing is the following:
– All vipaka vedana are sukha, dukkha, or upekkha.
– Somanassa and domanassa vedana are “mind-made” due to our gati. They are “samphassa-jā-vēdanā.” They do not arise in an Arahant.
