In the Bhagavad-gītā (14.27), the Lord explains His personal rays (brahmajyoti), the dazzling effulgence of His personal form, in this way:
- brahmaṇo hi pratiṣṭhāham
- amṛtasyāvyayasya ca
- śāśvatasya ca dharmasya
- sukhasyaikāntikasya ca
"I am the basis of the impersonal Brahman, which is immortal, imperishable and eternal and is the constitutional position of ultimate happiness." Brahman, Paramātmā and Bhagavān are three aspects of the same Absolute Truth. Brahman is the aspect most easily perceived by the beginner; Paramātmā, the Supersoul, is realized by those who have further progressed; and Bhagavān realization is the ultimate realization of the Absolute Truth. This is confirmed in the Bhagavad-gītā (7.7), where Lord Kṛṣṇa says that He is the ultimate concept of the Absolute Truth: mattaḥ parataraṁ nānyat. Therefore Kṛṣṇa is the source of the brahmajyoti as well as the all-pervading Paramātmā. Later in the Bhagavad-gītā (10.42) Kṛṣṇa further explains:
- atha vā bahunaitena
- kiṁ jñātena tavārjuna
- viṣṭabhyāham idaṁ kṛtsnam
- ekāṁśena sthito jagat
