One day a monk paid a visit to Tinh Khong (1091-1170), a Vietnamese Zen master, who was of the tenth generation of Vo Ngon Thong lineage, and asked:
-From old days it was talked about "direct pointing", what does that mean?
Looked at but cannot be seen - it is beneath form;
Listened to but cannot be heard - it is beneath sound;
Held but cannot be touched - it is beneath feeling;
These depthless things evade definition,
And blend into a single mystery.
In its rising there is no light,
In its falling there is no darkness,
A continuous thread beyond description,
Lining what can not occur;
Its form formless,
Its image nothing,
Its name silence;
Follow it, it has no back,
Meet it, it has no face.
