During the intensive yoga course I joined in 2011 at the Parmarth Niketan ashram in Rishikesh, I came across a profound and amazing stotra (hymn of praise) in Sanskrit. It is called Nirvana Shatakam (also known as Nirvana Shatkam, Atma Shatkam or Shivoham).
I was struck by the power of its words. So much truth in each stanza. The first time I heard it I immediately thought with excitement, “This is pure Advaita Vedanta philosophy! A Vedantic meditation, a song for enlightenment.”
Chanting it made me shed some tears and I even felt goosebumps appear on my skin.
