To make use of your mind to think conceptually is to leave substance and attach yourself to form
Huangbo XiyunConsider the sunlight. You may say that it is near, yet if you pursue it from world to world you will never catch it. You may say it is far, yet it is right before your eyes. Chase it and it always eludes you; run from it and it is always there. From this example you can understand how it is with the true nature of things.
Huangbo XiyunAll Buddhas and ordinary people are just one mind. This mind is beyond all measurements, names, oppositions: this very being is it; as soon as you stir your mind you turn away from it.
Huangbo Xiyun...Therefore it is said: 'The perception of a phenomenon IS the perception of the Universal Nature, since phenomena and Mind are one and the same.'
