Ūrdhva (Urdhva) is one of the names of God Śiva (Siva). according to Vāyupurāṇa (Vayupurana), Śukrācārya (Sukracharya), guru (teacher) of the Daitya (a type of demons), practiced austere tapasyā (tapasya; penance or asceticism ) for thousand years and thus pleased Mahādeva (Mahadeva). Mahādeva, please with Śukrācārya, granted him a boon. Then Śukrācārya started praising Mahādeva; and while uttering this hymn in praise, he addressed Mahādeva as Ūrdhva — one of his names in the hymn.
