dukkha

Clinging to the idea of a self is considered a mistake, and the root cause of dukkha, or suffering.

The first noble truth posits that dukkha (suffering) is a characteristic of existence in the realm of rebirth.

Jhanas (when in the positive direction), and dukkha or suffering (as caused by tanha or tension) when applied in the negative direction.

The three marks of reality in Buddhism are anatta(not-self), annica(impermanence), and dukkha(suffering/dissatisfaction).

To avoid getting too "down" by too much Dukkha meditation, Sympathetic Joy with one's and other's good qualities or good actions we can brighten the mind.

The first of the four noble truths set fourth by the Buddha: The truth of dukkha: Recognizing that suffering is a fundamental part of existence They even call Joy “hidden suffering”.

*Dukkha (Suffering)*: - Recognizing suffering in all beings fosters compassion, but it doesn't negate the need for judgments.

* Dukkha: This is the most dangerous trap in Buddhism.

Because the purpose of meditation is not to make you happy, it is to help you understand the Satya/Truth to help you see beyond the Maya/Illusion and lead you towards Moksha/Liberation (from Suffering/Dukkha if you are Buddhist, from Punarjanam/Reincarnation if you are Hindu).
