“In a mere one-pointed concentration I fail to see
The potency to cut the root of cyclic existence;
Yet with wisdom devoid of the path of tranquil abiding,
No matter how much one may probe, the afflictions will not be overcome.
So this wisdom decisively penetrating the true mode of being,
The learned ones saddle it astride the horse of unwavering calm abiding;
And with the sharp weapon of reasoning of the Middle Way free of extremes,
They dismantle all locus of objectification of the mind grasping at extremes;
With such expansive wisdom that probes with precision,
The learned ones enhance the wisdom realizing the suchness.
I, a yogi, have practiced in this manner;
You, who aspire for liberation, too should do likewise.”
