The Most Excellent Mirror Samadhi

The sage will tell a trainee, who is feeling they are low and all inferior,
That on their head there gleams a jewelled diadem, and on their body rich robes hang and at their feet there is a footrest.
If the trainee hears this teaching with surprise and doubt,
The sage assures them that of cats there are some kinds, as also some white cows, that perfect are just as they are.
A master archer hits a target at a hundred yards because they skill possess
But, to make to meet two arrows in mid-air, head-on, goes far beyond the skill of ordinary mind.
