Typing

On page One Thirty four, in review, there are three types of teenie tinies (Rupa-kalapas)

1)  Those made of 8 elements
2)  Those made of 8 elements plus the life force
3)  Those made of #2 plus a tenth

On this page, Sayadaw breaks down a few types of 'Rk's of type #3:

a: Eye, ear, nose, tongue, body ones with the tenth being body-transparent element,
b: Heart ones, with the tenth being an opaque element, also the sense base;  like so: an object strikes upon a sense door and the mind door at the same time, as in a color object is known by mind consciousness, then eye consciousness, then further mind consciousness.   Also there are some objects that strike the mind only (all other objects in the world apart from the five types of color, sound, smell, taste, touch dhammas; which are: the sense doors, subtle materiality, consciousness, mental factors, nirvana and 'the infinite number of concepts')
c: Male/female Rk's..... the male one found only in males, the female only in females.


Here is an interesting book; has a lot of those Thai 'ball of light' things;
