The inner voice is something which cannot be described in words. But sometimes we have a positive feeling that something in us prompts us to do a certain thing. The time when I learnt to recognise this voice was, I may say, the time when I started praying regularly.
My varnashram refuses to bow the head before the greatest potentate on earth, but my varnashram compels me to bow down my head in all humility before knowledge, purity, before every person where I see God face to face.
