of Brahmanism and can be described as Hinduism. Smarta as a tradition emphasized all gods as equal and different ways of perceiving the all-pervasive metaphysical impersonal Brahman. Modern Hinduism In recent times bhakti cults have increasingly become popular with the smartas. Vaitheespara notes the adherence of the Smarta Brahmans to "the pan-Indian Sanskrit-brahmanical tradition": Philosophy and practices Panchayatana Puja The Smartas evolved a kind of worship which is known as Panchayatana puja. In this Puja, one or more of the five Hindu Deities (Surya, Shiva, Vishnu, Ganesha and Adi Shakti) are the objects of veneration. The five symbols of the major Gods are placed on a round open metal dish called Panchayatana, the symbol of the deity preferred by the worshiper being in the center. A similar arrangement is also seen in the medieval temples, in which the central shrine housing the principal Deity is surrounded by four smaller shrines containing the figures of the other deities. Some of the Smartas of South India add a sixth god Kartikeya (See Shanmata). According to Basham, any upper-class Hindus still prefer the way of the Smartas to Saiva and Vaisnava forms of worship". Panchayatana puja is a practice that became popular in medieval India, and has been attributed to Adi Shankara. However, archaeological evidence suggests that this practice long predates the birth of Adi Shankara. Many Panchayatana mandalas and temples have been uncovered that are from the Gupta Empire period, and one Panchayatana set from the village of Nand (about 24 kilometers from Ajmer) has been dated to belong to the Kushan Empire era (pre-300 CE). The Kushan period set includes Shiva, Vishnu, Surya, Brahma and one deity whose identity is unclear. According to James Harle, major Hindu temples from 1st millennium CE embed the pancayatana architecture very commonly, from Odisha to Karnataka to Kashmir; and the temples containing fusion deities such as Harihara (half Shiva, half Vishnu) are set in Panchayatana worship style. Saguna and Nirguna Brahman According to Smartism, supreme reality, Brahman, transcends all of the various forms of personal deity. The Smartas follow an orthodox Hindu philosophy, which means they accept the Vedas, and the ontological concepts of Atman and Brahman therein. The Smarta Tradition accepts two concepts of Brahman, which are the saguna Brahman – the Brahman with attributes, and nirguna Brahman – the Brahman without attributes. The nirguna Brahman is the unchanging Reality, however, the saguna Brahman
