Buddha says

💐Words of the Buddha.

1] The meditator understands, "There has arisen in me this pleasant, unpleasant or neutral experience. It is composed, of a gross nature, dependent on conditions.

But what really exists, what is most excellent, is equanimity."

Whether a pleasant experience has arisen in him, or an unpleasant, or a neutral one, it ceases but equanimity remains.

M. 152, Indriya Bhāvanā Sutta.

2]  When his underlying conditionings of craving for pleasant sensation, of aversion toward unpleasant sensation, and of ignorance toward neutral sensation are eradicated, the meditator is called one who is totally free of underlying conditionings,

who has seen the truth, who has cut off all craving and aversion, who has broken all bondages, who has fully realized the illusory nature of the ego, who has made an end of suffering.

—S. XXXVI (II). i. 3, Pahāna Sutta.
