In plain words
Yajñāṅga and Yajñavāhana. He is called Bhūrbhuvaḥsvastaru because his three primary manifestations correspond to the three worlds of Bhūḥ, Bhuvaḥ, and Svaḥ. He is Tāra because He carries beings safely across the turbulent ocean of saṃsāra. He is Savitā as the ultimate generator of all existence, and Prapitāmaha as the father even of Brahmā, the grandfather of creation. He is Yajña because His very essence is sacrifice, Yajñapati as the supreme master of all sacred rites, and Yajvā because He abides within every ritual. He is also known as Yajñāṅga in His divine Boar incarnation, whose cosmic limbs constitute the sacred sacrifices.
