Sitting meditation
Sitting meditation does not mean sitting there idly, doing nothing, Most important of all, do not cling to the ideas that "I am meditation," "I am reciting the name Buddha" or I am practicing Zen and counting the breath", That we will be practicing with omnipresence of the sense of "self". If we continue to dwell on idea that "I am doing this and that, We are still clinging to erroneous and illusive thoughts and can never be genuinely free. In that way, just as the Sixth Patriarch Feinern says that "even if we meditate for thousands of year, the effect will be the same as cooking rocks or steaming sands---all useless in terms of getting ourselves to transcend the cycle of birth-and-death". Be attach our mind to nothing.
