SB 3.12.1
maitreya uvaca
iti te varnitah ksattah
kalakhyah paramatmanah
mahima veda-garbho ’tha
yathasraksin nibodha me
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Sri Maitreya said: O learned Vidura, so far I have explained to you the glories of the form of the Supreme Personality of Godhead in His feature of kala. Now you can hear from me about the creation of Brahma, the reservoir of all Vedic knowledge.
