“Having become a pure vessel by training in the general path,
Please bless me to enter
The holy gateway of the fortunate ones:
The supreme vajra vehicle.
At that time, the basis of accomplishing the two attainments
Is keeping pure vows and samaya.
As I have become firmly convinced of this,
Please bless me to protect these vows and pledges like my life.”
