--- dear CP kumar ji,
Welcome to our group. And thank you for uploading a file for all of
us already.

"I just wanted to ask learned members about the "nadi astrology". How
far the predictions derived from palm leaves are reliable?"

I do not know too much about this. From your question and the link
to your site, it seems you have a lot of knowledge and interest in
astrology. So I will shut up, or you will come to know the true
extent of my lack of knowledge and I will not be able to impress
people around!!
May be you can ask RR Bose on astroexpert. He has some discussion
group too, as does sanjay rath.

"Besides
purity of thoughts and good karma (already having "wasted"
significant span in this birth), how can one influence the course of
destiny for early liberation of soul?"

mantra is like a rough patch, and tantra is like slippery slope.
Seeking and getting the blessings of a guru. Ha, ha! I feel like a
blind person explaining the beauty of a rain bow!! May be I am
answering a question from the masters level while I am still in the
kinder garden!

Perhaps the easiest way is to give up this idea of liberation too.
As long as we work for something including liberation our quest
remains selfish. It is like I wish to be free, so I must be good. If
I do good to others good will come back to me, so I must be good. The
misinterpretation of karma theory has made us hindus very selfish. So
we feed go around doing this good and that good and become more and
more mean. Take the examples of offering milk to snakes whereas we
know that it is not their natural diet, or feeding dogs sweets on
Saturdays knowing fully well that the dog will develop allergies on
its body.

See, as long as we work with the idea of getting something in return
be it liberation or material happiness good karma will still produce
bondage. The only solution is loosing yourself and letting go- in
anything that appeals to you. Even loving your wife passionately may
be the answer!!
That said there is so much negative energy in and outside me that if
I do not chant I cannot even function like a normal human being. It
brings in good thoughts, and helps me handle my selfishness and
meanness and at least paves way for some good as I think my
liberation is several life times ahead –not something like two births.


"Love, Peace and Happiness"

May it all return to you too.
Jai gurudev
