Mahamudra cannot be taught.
But most intelligent Naropa,
Since you have undergone rigorous austerity,
With forbearance in suffering and with devotion to your Guru,
Blessed One, take this secret instruction to heart.
Is space anywhere supported?
Upon what does it rest?
Like space, Mahamudra is dependant upon nothing;
Relax and settle in the continuum of unalloyed purity,
And, your bonds loosening, release is certain.
