VaishnavismVaishnavism (Vaiṣṇavasampradāyaḥ) is one of the major Hindu denominations along with Shaivism, Shaktism, and Smartism. It is also called Vishnuism since it considers Vishnu as the sole supreme being leading all other Hindu deities, i.e. Mahavishnu. Its followers are called Vaishnavites or Vaishnavas (), and it includes sub-sects like Krishnaism and Ramaism, which consider Krishna and Rama as the supreme beings respectively. According to a 2010 estimate by Johnson and Grim, Vaishnavism is the largest Hindu sect, constituting about 641 million or 67.
Iṣṭa-devatā (Hinduism)Ishta-deva or ishta devata (Sanskrit: इष्ट देव(ता), , literally "cherished divinity" from iṣṭa, "personal, liked, cherished, preferred" and devatā, "godhead, divinity, tutelary deity" or deva, "deity"), is a term used in Hinduism denoting a worshipper's favourite deity. It is especially significant to both the Smarta and Bhakti schools, wherein practitioners choose to worship the form of God that inspires them. Within Smartism, one of five chief deities is selected.
VishnuVishnu (ˈvɪʃnuː ; Viṣṇu, ʋɪʂɳʊ), also known as Narayana and Hari, is one of the principal deities of Hinduism. He is the supreme being within Vaishnavism, one of the major traditions within contemporary Hinduism. Vishnu is known as The Preserver within the Trimurti, the triple deity of supreme divinity that includes Brahma and Shiva. In Vaishnavism, Vishnu is the supreme being who creates, protects, and transforms the universe. In the Shaktism tradition, the Goddess, or Adi Shakti, is described as the supreme Para Brahman, yet Vishnu is revered along with Shiva and Brahma.
