World Honored One, I remember when, as many kalpas ago as there are sands in the Ganges, there was a Buddha in the world named Contemplating the World’s Sounds. It was under that Buddha that I brought forth the Bodhi-resolve. That Buddha taught me to enter samadhi through a process of hearing and reflecting.

I received from that Thus Come One a transmission of the Vajra Samadhi of all being like an illusion, as one becomes permeated with hearing and cultivates hearing.
