Raju

The dominant flow of energy for a given person. This depends on past karma.

One "line" of Sukhmani brings tears to one's eyes... Guru Arjun..I have not the words...

Har ka Bhagat pargat nahi chhapay Such is the will of the Lord...

Stillness is the main factor. That said, some asanas help direct the flow of pran in the right direction...

Tiger skin is more suitable as an asan for those who have a more "lunar" disposition. For those of us with excess solar energy, the better asan is deerskin.

I recall being at a Satsang held by Sant Waryam Singh in Chandigarh, 2001. One of the UK visitors (highly evolved), could see auras and had to ask the great Saint to reduce his "jalal", so he could sit in his presence. During a Satsang, he saw a "chakar" and light behind the Saint while delivering a discourse to the Sangat. The person in question was only one step away from merging with the divine at the time (I was fortunate to be present during their conversations)... The meetings between these two great souls were a true blessing to witness. In other words, these things are the result of spiritual practice and show progress. However, one should focus on the goal of practice rather than the phenomenon of it.

Mukti is possible if one has evolved sufficiently in previous lifetimes. If your birthchart has Ketu in the twelfth, and well-positioned planets for spiritual progress, then there is a chance of good progress. That said, astrology is merely a tool and should not be abused or considered the be all, end all, of course.
