I fortunately received the empowerment and lung for mantra today. Although i heard the mantra 3 times from lama (Sherab Gyaltsen Rinpoche) i could not memorize it because it's quite complicate.
I miss 2 words: om benza mahakala xxx xxx phat hung hung
He said it's the one he received from Kalu Rinpoche if this can help. It's not the Shangpa mahakala. Please help me i can't find the mantra written down because of it is secret.
