I and my friend have a question about 'yoniso manasikaara' (wise attention) in Pali Abhidhamma.
Where does '(a)yoniso manasikaara' start to function in terms of the theory of cittaviithi in Pali Abhidhamma, manodvaaraavajjana or javana?
Ledi Sayadaw gives a relevant sentence in his Paramatthadiipanii (p. 93 CSCD),
Manodvaaraavajjanam. javanapat.ipaadako naama.
Tam. pi javanasantatim. aaramman.e pat.ipaadeti yojetiiti. Idameva dvayam. tattha tattha yoniso manasikaaroti ca ayoniso manasikaaroti ca vuttam.
In fact I don’t fully understand its meaning, but it seems he suggests that Manodvaaraavajjana has two types: yoniso manasikaara and ayoniso manasikaara. But isn’t Manodvaaraavajjana always a citta which is rootless, functional, accompanied by equanimity? Why are the differences between ‘yoniso’ and ‘ayoniso’ in Manodvaaraavajjana?
Any comment is much appreciated.
