"This is why in the practice of shi-nè we let go and let be. We do not encourage thought, yet neither do we block it. We treat the process of thought gently. We let thoughts come, and we let thoughts go. We translate shi-nè as 'remaining uninvolved.' If thoughts arise, one lets them arise; if they dissolve, one allows their dissolution. If thoughts are present, one allows their presence. One does not add to them or protract them. If thoughts depart, one does not detain them. One treats them as welcome yet transient guests. One treats thought as a fire that has served its purpose -- one merely ceases to add further fuel. If one stops fueling thought with active involvement, thought settles and one enters into a calm and undisturbed state"
