I see, Lal. Thank you for your help and explanation.
I see vinnana as occurring at least three times within a single PS cycle.
The first time is of course as vinnana, or more exactly kamma vinnana, which is a mano vinnana.
The second time it appears as a sub-factor of phassa, for example cakkhu vinnana arises when there is phassa between vanna rupa (rupa rupa) and the cakkhu indriya. This vinnana is a vipaka vinnana, and may be cakkhu vinnana, sota vinnana, ghana vinnana, jivha vinnana, kaya vinnana or mano vinnana.
If beings get attached to the vipaka vinnana via tanha, another kamma vinnana may result as upadana sets in. This kamma vinnana is part of the vinnanakkhandha, which makes up part of the pancupadanakkhandha of the being. This kamma vinnana either is or may result in the formation of a kamma bija in the kamma bhava, which can then bring future vipaka vinnana when jati sets in.
Is this correct? I would also like to point out that under this ‘Questions about Puredhamma Posts’ section, I have started another query about one type of micca ditthi–thinking that making offerings to devas and other beings have no benefits (Mahā Cattārisaka Sutta (Discourse on the Great Forty)). You may have missed it since both queries fall under the same section.
Thank you very much in advance for your kind responses.
