Pratybhijjna is to cognise oneself as Shiva as that is the stuff of one's being. Though, I think that any practice can't yield this result without its blessing. After all, only He cognises his original reality. And the Self in us (being a spark of the divine) is the pivot of our life. As Lalleshwari wrote:
Don't speak of Hindu or Musulman
If you are wise, know yourself
That is the recognition of the true Friend .
OM NAMAH SHIVAYA
