Why do I believe in Tantra so much? Because it is experiential. I am experiencing it. It’s not about believing in order to see as with most religions and paths, it’s seeing leading to believing, because you are experiencing!
This is also why the body is not separated from the practice. Our sensory experience is used in order to bring about our understanding. We integrate the material and the spiritual and transcend duality.
The truth will appear and synchronize to your experience giving you clarity and surety. The joy you feel will be confirmation that this is truth because you are reaching the ultimate goal of happiness. Not through transient elevated emotional states but through a peaceful unattached acceptance that is unperturbed by circumstances and change.
