The nucleus of Astrology is Spirituality. Therefore, any thing that we discuss in Astrology has deep roots in Spirituality and epicenter of Astrology is the doctrine of Karma.
I have given links of a recent presentations including a talk delivered in Orlando, US. Apart from these two presentations, a phone-in live Prasna Shasthra programme in a divine channel Sri Sankara TV in Kannada language is also included.
I hope the links will interest you.
