³⁰Lindsay and Creswell (2017), while emphasizing the importance of acceptance in mindfulness training, use the term almost synonymously with “nonreactivity”. Hayes and Pierson (2005) define acceptance as “an open and noncontrolling stance toward all experiences”, which shows explicitly the connection to control. Meanwhile, Peacock (2018) offers an interesting interpretation of the goal of early Buddhist philosophy in terms of “freedom from enthrallment to reactive patterns”, which places nonreactivity at the very center of Buddhist training. It should be noted, however, that in actual meditation training, it is often recommended that an active, positive feeling (possibly what is called loving-kindness) is developed towards mental phenomena (Grabovac et al., 2011; Hofmann et al., 2011). It may be necessary to actively develop such positive feelings to counteract the inherent tendency to aversion and judgement; simply trying to refrain from negative judgements and practising meditation based on observation may not remove them efficiently (Samyutta Nikaya 10.4).
