In my recent question, I asked about the pādas of the yuga. This time my question is about śakas (era). Many of you are aware that we live in the śālivāhana śaka era. Even though the current year according to Gregorian calendar is 2017, the present year in śālivāhana śaka is 1939.
Now my questions are:
Who are the śaka puruṣā for the current yuga?
On what basis is a śaka started?
How are these persons identified? Should they have performed great deeds to qualify?
