mahān prabhur vai puruṣaḥ sattvasyaiṣa pravartakaḥ sunirmalām imām prāptim īśāno jyotir avyayaḥ
“The Supreme Personality of Godhead is Mahāprabhu, who disseminates transcendental enlightenment. Just to be in touch with Him is to be in contact with the indestructible  brahmajyoti .” (Śvet. Up. 3.12)
(3) From the  Muṇḍaka Upaniṣad  (3.1.3):
yadā paśyaḥ paśyate rukma-varṇaṁ kartāram īśaṁ puruṣaṁ brahma-yonim
“One who sees that golden-colored Personality of Godhead, the Supreme Lord, the supreme actor, who is the source of the Supreme Brahman, is liberated.”
(4) From  Śrīmad-Bhāgavatam :

He removes the distresses of His devotees and satisfies their desires. He, the abode of all holy places and the shelter of all sages, is worshipable by Lord Śiva and Lord Brahmā.

He went into the forest to deliver the fallen souls, who are put into illusion by material energy.” ( Bhāg.  11.5.34)
