Among delusions negated in the Heart Sutra is Karma, or the causal chain which co-creates the circumstances of our existence. It is only with the first link that any karma exists at all and yet, the chain of cause and effect can never be broken.
“Why” is a question asked only in a sequence of delusion. The purpose of meditation practice is not to rearrange or answer the question, it is to extinguish the asker and the asked. If and when it returns in the natural course of our day, its beginning, middle and end can be seen and the snake is once again rope.
The conventional person sees this causal chain as Karma, their karma. There is, of course, no “their” and no “karma.” We feel we can somehow ‘sort’ life out by sorting our rumination about people, places and things, not seeing that the rumination must be cut off at its source.
To see “no causal link, no end of causal link” in meditation is the first step. To live “no causal link, no end of causal link” is to overcome ignorance regularly, to see the entire situation in its brilliant emptiness. All mind, inside and outside, must be seen the same way; the practitioner’s stance must be taken beyond all mind while existing right in the middle. Taking a stand beyond your own mind is the same as taking a stand beyond the minds of others.
