However, the Vaishnava commentator, Parasara Bhattar, a follower of Ramanujacharya has interpreted the names "Shiva" and "Rudra" in Vishnu sahasranama to mean qualities or attributes of Vishnu, and not to indicate that Vishnu and Shiva are one and the same God. Vaishnavas worship Vishnu in his four-armed form, carrying conch, disc, flower and mace in his hands, believing that to be the Supreme form. However, Smarthas do not subscribe to this aspect or personification of God, as Smarthas say that God is Nirguna and thus devoid of form. Additionally, they believe that God is not limited by time nor limited by shape and color. Vaishnava traditions are of the opinion that Vishnu is both unlimited and yet still capable of having specific forms, as to give arguments to the contrary (to say that God is incapable of having a form) is to limit the unlimitable and all-powerful Supreme.
