Anushasana Parva 157.17

The celestials headed by Indra sang his praises when he lifted up thc Gobardhana mountains for protecting the cowherds of Vrindavan against the incessant showers that Indra poured in anger. He is, O Bharata, the one Blessing to all creatures. He, O Bharata, having entered the old Brahmacave, saw from that place the original cover of the world in the beginning of time.
