In the Western world where the glories of Lord Caitanya are relatively unknown, one may inquire, "Who is Kṛṣṇa Caitanya?" The scriptural conclusion in answer to that question is that He is the Supreme Personality of Godhead. Generally in the Upaniṣads the Supreme Absolute Truth is described in an impersonal way, but the personal aspect of the Absolute Truth is mentioned in the Īśopaniṣad, where, after a description of the all-pervading, we find the following verse:
- hiraṇmayena pātreṇa
- satyasyāpihitaṁ mukham
- tat tvaṁ pūṣann apāvṛṇu
- satya-dharmāya dṛṣṭaye
"O my Lord, sustainer of all that lives, Your real face is covered by Your dazzling effulgence. Kindly remove that covering and exhibit Yourself to Your pure devotee." (Śrī Īśopaniṣad, Mantra 15)
