yathā purastād vyākhyāsye
pādmaṁ kalpam atho śṛṇu
The present duration of a kalpa of Brahmā is called the Varāha-kalpa or Śvetavarāha-kalpa because the incarnation of the Lord as Varāha took place during the creation of Brahmā, who was born on the lotus coming out of the abdomen of Viṣṇu. Therefore this Varāha-kalpa is also called Pādma-kalpa, and this is testified by ācāryas like Jīva Gosvāmī as well as Viśvanātha Cakravartī Ṭhākura in pursuance of the first commentator, Svāmī Śrīdhara. So there is no contradiction between the Varāha and the Pādma-kalpa of Brahmā.
