Tantric work by Saraha

If it [the Truth] is already manifest, what's the use of meditation?
And if it is hidden, one is fust measuring darkness. (20)
Mantras and tantras, meditation and concentration,
They are all a cause of self-deception.
Do not defile in contemplation thought that is pure in its own nature,
But abide in the bliss of yourself and cease those torments. (23)
Whatever you see, that is it,
In front, behind, in all the ten directions.
Even today let your master make an end of delusion! (28)
The nature of the sky is originally clear,
But by gazing and gazing the sight becomes obscured. ( 34)
