Birth by transformation
BIRTH BY TRANSFORMATION ‘Birth by transformation’: This refers to metamorphic births,such as those of devas (gods), asuras, hungry ghosts, and inhabitants of hell, the bardo, and the Pure Lands.”
Chan: 475
“When a being is suddenly born with all the sense-organs and limbs of a complete body, without depending on anything such as an egg or a womb, he is said to be born by transformation, or born ethereally. All hell-dwellers, devas, and beings in the Bardo and the Pure Lands; some dragons, garudas, and hungry ghosts; and humans born at the very beginning of a kalpa are born in this manner.”
birth by transformation (Sanskrit: Upapaduka; Pali: Opapatika; Chinese: 化生; Standard Tibetan: Rzus-skyes)—miraculous materialization, as with most devas.
