Is it thoughts?

Is it "consciouness"?

Is it awareness?

Is it me?

Yuan Yin Lao Ren:

In the past there was a Master who contemplated, "what is the original face before my parents were born?" He contemplated for many years, but did not awaken. Later on he encountered a great noble person and requested for his compassionate guidance. The noble one asked: "What koan did you contemplate?" He replied: "I contemplated what is the original face before my parents were born?" Noble one replied: "You contemplated too far away, should look nearby." He asked: "How should I look nearby?" Noble one replied: "Don't look into what is before your parents were born, need to look at: before a thought arise, what is it?" The Zen practitioner immediately attained great awakening.

Everyone that is sitting here, please look at what is this before a moment of thought's arising? IT is radiating light in front of everybody's [sense] doors, the brightness radiates everything yet is without the slightest clinging, nothing is known and nothing is seen yet it is not similar to wood and stones, what is This? IT is right here shining in its brilliancy, this is awakening to the Way. Therefore it is said, "the great way is not difficult, just cease speech and words"!
