Whether one is rich or poor, famous or unknown, bright or dull, wise or foolish, religious or an atheist, each experiences pleasures and pains, joys and sorrows, tears and laughter, victories and defeats in their life.
At some point, one may ask “What is all this?”
“Who am I that has all these experiences?”
Thus, as if compelled, the sages start to reflect on the nature of their existence and the mind.
The quest to know the nature of existence starts us on the journey to our own Heart, which is indeed the Universal Heart.
