Sammà-saïkappa and sammà-diññhi together constitute pa¤¤àsikkhà

Review of Bodhipakkhiya
Although there are 37 enlightenment-factors, the essential
elements amount to only 14 – namely, sati, vãriya, chanda, citta,
pa¤¤à saddhà, ekaggatà, pãti, passaddhi (both kàya and citta),
tatramajjhattatà, vitakka, sammà-vàcà, sammà-kammanta and sammààjãva.
Of these 14 essetial elements, pãti, passaddhi, tatramajjhattatà,
vitakka, 3 viratis, chanda and citta occur only as one factor each.
Vãriya occurs 9 times, i.e. as 9 factors; sati as eight factors;
ekaggatà as 4 factors; pa¤¤à as five factors; and saddhà 2 as factors.
Please see Table 7.2.

Five categories will be dealt with here. They are Khandha,
Upàdànakkhandha, âyatana, Dhàtu and Ariyasacca.
1 Five Khandhas (Five Aggregates)
‘Khandha’ means group or aggregate. Buddha has summed up
all the physical and the mental phenomena of existence into
five groups or aggregates.
1 Råpakkhandha –
corporeality group consisting of 28 råpas.
2 Vedanàkkhandha –
feeling group consisting of sukha-vedanà, dukkha-vedanà,
somanassa-vedanà, domanassa-vedanà and upekkhà-vedanà.
