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
"But what need is there, Arjuna, for all this detailed knowledge? With a single fragment of Myself I pervade and support this entire universe." Thus by His one plenary expansion, the all-pervading Paramātmā, the Lord maintains the complete material cosmic creation. He also maintains all manifestations in the spiritual world. Therefore in this śruti-mantra of Śrī Īśopaniṣad, the Lord is addressed as pūṣan, the ultimate maintainer.
The Personality of Godhead, Śrī Kṛṣṇa, is always filled with transcendental bliss (ānanda-mayo 'bhyāsāt). When He was present at Vṛndāvana in India five thousand years ago, He always remained in transcendental bliss, even from the beginning of His childhood pastimes. The killings of various demons-such as Agha, Baka, Pūtanā and Pralamba-were but pleasure excursions for Him. In His village of Vṛndāvana He enjoyed Himself with His mother, brother and friends, and when He played the role of a naughty butter thief, all His associates enjoyed celestial bliss by His stealing. The Lord's fame as a butter thief is not reproachable, for by stealing butter the Lord gave pleasure to His pure devotees. Everything the Lord did in Vṛndāvana was for the pleasure of His associates there. The Lord created these pastimes to attract the dry speculators and the acrobats of the so-called haṭha-yoga system who wish to find the Absolute Truth.
