65. Literally, “endowed with a cranial protuberance (uṣṇīṣa) that cannot be [fully] seen when looked at.” This alludes to the belief in the wide-ranging powers of the Buddha’s uṣṇīṣa. Since it extends all the way to the realm of gods, thereby enabling the Buddha to control all the realms with his body, its full extent cannot be seen from earth. The Mañjuśrī­mūla­kalpa elaborates on the powers of the Buddha’s uṣṇīṣa at considerable length.
