No idea what is left?
Cloud of Jewels Sutra
Shamata is one-pointed attention. Vipashyana (insight) is the distinct discernment of phenomena, correctly and exactly as they are.
Shamata curbs disturbing emotions, while vipashyana utterly purifies them.
Nagarjuna
There exist no phenomena that do not originate in dependency.
Therefore there exist no phenomena that are not empty.
King of Samadhi Sutra
Like a star, an aberration, or a flame,
Like a magical illusion, a dewdrop, or a water bubble,
Like a dream, lightning, or a cloud,
Know allthings to be this way.
Chandrakirti
First saying "I," beings fix upon the self,
With "that is mine!" they long for things,
Cycling helplessly like buckets of a water wheel.
I bow to One who lives compassion for such beings!Compassion alone is the seed for the crop of buddhas,
It is the water that makes their enlightenment grow,
And it ripens to fruitition in eternal happiness.
Thus first of all I praise compassion!
When no idea of anything exists, what is left?
