HRIDYAMANTHAN (The Churning of Heart) is a comprehensive literary work, authored by Raghunandan Rao. Hridyamanthan exhibits one similarity to Samudramanthan (The Churning of Ocean). This similarity is pursuant to cause of action, both oozing out Vish (poison) at the first instance and ending up with Amrit (elixir or nectar). In contrast to one time action of Samudramanthan, Hridyamanthan is a continuous process, oscillating all the time between two end essence of Amrit vs Vish, and in between some more, originating from inner concentrate of positivity and negativity in Purush (Male) and Prakirti (Female)- the supreme creature on the earth.
