Śrī Caitanya Caritamrta · Text Ādi 5.61
অতএব কৃষ্ণ মূল–জগৎকারণ ।
প্রকৃতি—কারণ যৈছে অজাগলস্তন ॥ ৬১ ॥
ataeva kṛṣṇa mūla-jagat-kāraṇa
prakṛti — kāraṇa yaiche ajā-gala-stana
Therefore Lord Kṛṣṇa is the original cause of the cosmic manifestation. Prakṛti is like the nipples on the neck of a goat, for they cannot give any milk.
