On my Personal Tsok Day this week, I read a song from the 'Songs of Innate Freedom: Volume 5'. It's a book of songs written by Indian mahāsiddhas and I opened the book to Song 153, by the great master Dīpamkara.
"Those completely ignorant about it
Circle through threefold existence -
I pay homage to the dharmadhātu*
That dwells in all sentient beings 
By virtue of being the natural nirvana,
the dharmadhātu is without middle or end,
seen by insights sharp eye free of thoughts,
without the blurriness of dullness and agitation 
Just as a lamp that's sitting in a vase
does not illuminate even a little bit,
the dharmadhātu dwelling in the vase
of the afflictions does not shine 
From whichever of its sides
holes are punched into this vase
it is from just these very sides
that the nature of light beams forth 
Seeing the abundance of the tīrthikas
with their seeds of being harmful,
is there anyone not feeling compassion
for persons wishing for liberation?
Hence, those who strive for liberation
should behold the dharmadhātu." 
*Dharmadhātu is the purified mind in its natural state, free of obscurations.
