Colophon (following MHTL, no. 171878):
rang don tsam du gsang ba ’dus par yang ||
dga’ bar mi bgyid gzhan gyi don ’gyur na ||
mdos glud gto chog rnams kyang nyams len du ||
khyer pa theg chen chos lugs ma yin nam ||
Not taking pleasure even in Guhyasamāja [practice]
For one’s own benefit alone,
Practicing even mDos, Glud, and gTo [rituals]
If it turns out to benefit other [beings]; is this not the Mahāyāna religious tradition?
Wow! A beautiful idea in my view! The author of the verse is unknown to me.
