Contemplate at ease to find wisdom.
Investigating Chan means learning to contemplate. What are we to contemplate? Contemplate your illuminating prajna. I am teaching you to be mindful of the present and to contemplate yourself, not to contemplate others. Contemplate whether you are here or not? If you are here, then you can sit and investigate Chan, working hard at cultivation. If you are not here, then you are indulging in false thinking and are daydreaming. Even though you are physically in the Chan hall, your mind has gone to New York sightseeing, or to Italy for a holiday. Your mind goes everywhere, climbing on conditions. Hence, you are not at ease.
To contemplate at ease is to be a Bodhisattva. Not contemplating at ease, you are an ordinary person. To contemplate at ease is to experience the divine. If you do not contemplate at ease, you may end up enduring the hells. If you contemplate at ease and your mind does not escape, then you can practice profound prajna paramita. By physically investigating Chan continuously without cease, you are also practicing profound prajna, and discovering your wisdom. Once you activate your inherent great wisdom, then you can reach the other shore.
The secret to Chan investigation is to focus on it day and night. Focus on what? “Who is mindful of the Buddha?” Investigate this today and again tomorrow. Even though you practice profound prajna paramita in the Chan hall everyday, you may not taste the flavor of Chan right away. It takes a long time to accomplish that. Only when you have gained sufficient skill in practicing profound prajna paramita will you be able to illuminate the five skandhas and see that they are all empty.
