Vijnana Bhairava 93 Awakening Through Pain

The practice of awakening through (intense) pain  :

kiṃcid aṅgaṃ vibhidyādau tīkṣṇasūcyādinā tataḥ |

tatraiva cetanāṃ yuktvā bhairave nirmalā gatiḥ || 93 ||

"First pierce any part of the body

with a sharp needle, for instance.

Then fix your awareness right there :

immaculate insight of the divine (will happen)."
