As long as we are resideing and clinging to the realm of "I","ME","MINE", and other, we are residing somewhere next door to reality & it creates great suffering. We can look into the mirror of the dhamma and see the painful contraction that accompanies"ME"&"MINE"&"THEIR'S" and let go & come to know the truth of interconnectedness & the reality of no separate, no solid, no static "self", and take the great relief & ease in this truth.
Equanimity is resting the mind before it falls into extremes of reactivity. The spacious, calm balance of equanimity can contain both the joys and sorrows of life— supporting mindfulness and the opening to deeper wisdom when we open to “how it is.” Moment to moment, equanimity leads to a great respect and to alignment with the truths that liberate.
Although humans have a bias toward falsely seeing permanence, we can develop the insight into the truth of impermanence. In the depths of meditation, we are able to discern the moment to moment dissolution of our experience at the six sense doors.
