parimÄṇaá¹ ca kÄlasya
kalpa-lakṣaṇa-vigraham

pÄdmaá¹ kalpam atho śṛṇu
parimÄṇam - measurement; ca - also; kÄlasya - of time; kalpa - a day of BrahmÄ; laká¹£aṇa - symptoms; vigraham - form; yathÄ - as much as; purastÄt - hereafter; vyÄkhyÄsye - shall be explained; pÄdmam - by the name PÄdma; kalpam - the duration of a day; atho - thus; śṛṇu - just hear.
The present duration of a kalpa of BrahmÄ is called the VarÄha-kalpa or ÅšvetavarÄha-kalpa because the incarnation of the Lord as VarÄha took place during the creation of BrahmÄ, who was born on the lotus coming out of the abdomen of Viṣṇu. Therefore this VarÄha-kalpa is also called PÄdma-kalpa, and this is testified by ÄcÄryas like JÄ«va GosvÄmÄ« as well as ViÅ›vanÄtha CakravartÄ« ṬhÄkura in pursuance of the first commentator, SvÄmÄ« ÅšrÄ«dhara. So there is no contradiction between the VarÄha and the PÄdma-kalpa of BrahmÄ.
