A small bird with a red bonnet on its head came and perched on a rock opposite us. It waved its tail, turned its head anxiously in all directions, then glanced directly at us and as it did so, it grew bold and began to whistle softly, tauntingly at first; but soon it threw back its head, swelled its throat, and gazing at the sky, the light, burst into song with abandon. Everything vanished; nothing remained in the world save this bird and God: God, and a beak that was singing.
This tenderness for life, bodhichitta, awakens when we no longer shield ourselves from the vulnerability of our condition, from the basic fragility of existence. It awakens through kinship with the suffering of others. We train in the bodhichitta practices in order to become so open that we can take the pain of the world in, let it touch our hearts, and turn it into compassion.
