He says in the Sutra, there is a particular term which points at our capacity for tolerating this world of suffering, although we recognize that this is a world of suffering, we continue to put up with it. Not only that, we are willingly tolerant of suffering, we remain attached to the concerns of worldly life, the worries, the vanities and the discriminations we use to judge one another. This is a world where we endlessly cope with suffering and rarely go beyond it. Likewise, a practitioner of chan may know very well that wandering discursive thoughts are potentially harmful, but nonetheless, she may remain remain positively attracted to them. After all, they're amusing when told not to entertain such tantalizing ideas and to think of nothing, the practitioner students find soon finds practice very boring. For example, we've agreed not to talk to one another. We know very well that talking causes us to lose our meditative focus. Nonetheless, situations arise in which a few remarks are passed, we cannot resist prolonging the interaction, interaction with a few more words in reply. It seems such an enjoyable thing, since we are indeed serious about practice, we should not think lightly of these warnings. If we heed them, we can go beyond knowledge and true practice can begin.
