Open acceptance can be defined as the ability to accept situations that are outside of our control without judging them, which in turn reduces the suffering that is caused by them.
Open acceptance is based on the notion that suffering comes not directly from pain, but from one’s attachment to the pain. It has its roots in Buddhism and the paradigm put forth by that acceptance is the first step towards change.
Rather than being attached to a painful past, radical acceptance suggests that non-attachment is the key to overcoming suffering. Non-attachment does not mean not feeling emotions. Rather, it refers to an intention of not allowing pain to turn into suffering. This means watching your thoughts and feelings to identify when you are allowing yourself to feel worse than is necessary.
The lack of judgment that is an important part of acceptance does not involve approval of the situation. Instead, it involves accepting reality for what it is and not getting caught up in an emotional reaction to that reality. Open acceptance is not an easy practice at all. In fact, it can require a lifetime of practice in order to truly get a handle on it.
