Anahata.

Anahata is the heart chakra in the classical seven-chakra map drawn from tantric and yogic tradition. The Sanskrit word means "unstruck," a reference to a sound that arises without two things striking together, which the old texts use as a metaphor for the steady inner note of the heart.

It sits at the centre of the chest, between the lungs, and is traditionally pictured as a green twelve-petalled lotus. In modern crystal practice it is the seat of love (for self, for others, for the world), compassion, forgiveness, and grief. Stones reached for here tend to be green or pink: rose quartz, green aventurine, rhodonite, emerald, and jade are the common choices.

When practitioners speak of an anahata that is "closed" or "guarded," they usually mean a period of withdrawal after loss, betrayal, or burnout. Working with the heart chakra is rarely about forcing openness. It is about giving the chest a little more room to breathe, and trusting the heart to settle in its own time.
