The Supreme Lord
ईश्वरः परमः कृष्णः सच्चिदानन्दविग्रहः। अनादिरादिर्गोविन्दः सर्वकारणकारणम्॥
īśvaraḥ paramaḥ kṛṣṇaḥ sac-cid-ānanda-vigrahaḥ anādir ādir govindaḥ sarva-kāraṇa-kāraṇam
Krishna is the supreme Lord. His form is being, awareness, bliss. He is without beginning. He is the beginning. Govinda is the cause of all causes.
The first verse of the surviving fifth chapter. The whole hymn unfolds from this single sentence. Krishna is not a creature of God. Krishna is God, in the form that loves and can be loved.
The four words that name him: paramaḥ, supreme; sac-cit-ānanda, being-awareness-bliss; anādiḥ ādiḥ, beginningless beginning; sarva-kāraṇa-kāraṇam, the cause of all causes. The Goswāmīs of Vrindavan would build seventy years of theology on this one verse.
