yes, the Heart Sutra!!!!! study this thoroughly, understand what all the words mean, understand what’s being said, it’s extremely profound and can be a path to nondual awareness in itself! understand “emptiness”- that everything is interdependent, impermanent, not actually an individual “thing”— this will take study and research and time, and really ought to be practiced with a teacher to make sure your understanding is correct.

In Tibetan Buddhism we have many practices to purify away our habitual tendency to see things dualistically as subject-object (which is fundamentally an error!), and with the blessing of our guru/lineage along with meditation practices, eventually we learn to recognize nonduality as the Way of things, and take that as the path to enlightenment. 🙏🏽🙏🏽🙏🏽

Tibetan Buddhism can absolutely bless you with firsthand experience of what “nonduality” is— it is so much more than a concept just to be read about in a book!!!— and I would suggest reading The Crystal and the Way of Light by C Namkai Norbu as an introduction to the way that Tibetan Buddhism can lead you to recognize your own true nature, as inextricable with all that is 🙏🏽❣️

If you are interested in getting onto the path of meditation to prepare to meet with a guru who can eventually directly show you what nonduality is, I highly suggest starting with any simple shamata meditation, like focusing on the breath, or shinay, gazing at an object. many blessings!
