Dear Satish,
Laghu parasarai also says
" 4. The learned should make themselves familiar with the fundamentals
of Astrology through other works. Here only the specific principles
will be explained."
Ash : Maybe because 1:7 relationship is fundamental. 7th sign from
any sign is enemy. Sign of exaltation is opposite that of its
debilitation and this is for all.
Maybe this is basic info that one is expected to know and here only
general things are given.
Nothing about Ashtakavarga is given either.
Cheers !!!
