In the beginning, Krishna said to Brahma the creator of the universe:
Sri Chaitanya Charitamrita, Adi-Lila Chapter 1 Text 52
যাবানহং যথাভাবো যদ্রূপগুণকর্মকঃ । তথৈব তত্ত্ববিজ্ঞানমস্তু তে মদনুগ্রহাৎ
yavan aham yatha-bhavo yad-rupa-guna-karmakah tathaiva tattva-vijnanam astu te mad-anugrahat
quoting Srimad Bhagavata Purana 2.9.31: “Whatever is My size or dimension (yavan), whatever is My nature or essence (yatha-bhavah), whatever My forms, qualities, and activities (rupa-guna-kriyah), whatever all of this may be — that reality, in its entirety, is tattva-vijnana (realized knowledge of the Eternal Truth about Me [Sri Krishna]). By My mercy you will understand this in full. Through gradual progress in Sadhana-Bhakti, and through the increase in the intensity of Prema, one progresses in tasting My sweetness (madhurya); thereafter, in the land of Braja, you will directly experience My most perfect form (Swayam-rupa) — Krishna.”
Amrita-Pravaha Bhashya (the commentary of Srila Bhaktivinode Thakur):
52। আমার স্বরূপ, আমার লক্ষণ, আমার রূপ, গুণ ও লীলা যে-প্রকার, সেই সকলের তত্ত্ববিজ্ঞান আমার অনুগ্রহে তুমি প্রাপ্ত হও।
52. amar swarup, amar lokkhan, amar rup, gun o lila je-prakar, sei sokoler tattvabiggyan amar anugrahe tumi prapto hao.
By My mercy, you will realize knowledge of My essential identity (swarup), My qualities (guna), form (rupa), and pastimes (lila), along with the tattvas underlying each.
