Vaishnavism (Devanagari: ) is a tradition of Hinduism, distinguished from other schools by its worship of Vishnu or his associated avatars, principally as Rama and Krishna, as the original and supreme God. This worship in different perspectives or historical traditions addresses God under the names of Narayana, Krishna, Vasudeva or more often "Vishnu", and their associated avatars. Its beliefs and practices, especially the concepts of Bhakti and Bhakti Yoga, are based largely on the Upanishads, and associated with the Vedas and Puranic texts such as the Bhagavad Gita, and the Padma, Vishnu and Bhagavata Puranas.The followers of Vaishnavism are referred to as Vaishnava(s) or Vaishnavites. A large percentage of Hindus are Vaishnavas, with the vast majority living in India. Awareness, recognition, and growth of the belief has significantly increased outside of India in recent years. The Gaudiya Vaishnava branch of the tradition has significantly increased the awareness of Vaishnavism internationally, since the mid-1900s, largely through the activities and geographical expansion of the Hare Krishna movement, primarily through ISKCON and more recently, through several other Vaishnava organizations conducting preaching activities in the WestBhagavatism, early Ramaism and Krishnaism, merged in historical Vishnuism, a tradition of Historical Vedic religion, distinguished from other traditions by its primary worship of Vishnu. Vaishnavism, is historically the first structured Vaishnava religion as "Vishnuism, in a word, is the only cultivated native sectarian native religion of India." Although it is usual to speak of Vishnu as the source of the avataras, this is only one of the names by which the god of Vaishnavism is known. The other names include Narayana, Vasudeva and Krishna; each the name of a divine figure with attributed supremacy, which each associated tradition of Vaishnavism believes to be distinct. For example, in the Krishnaism branch of Vaishnavism, such as the Gaudiya Vaishnava, Nimbaraka and Vallabhacharya traditions, devotees worship Krishna as the supreme form of God, Svayam Bhagavan, in contrast to the belief of the devotees of the Vishnu tradition.Supreme God Vishnu, as commonly depicted in his four-armed formThe principal belief of Vishnu-centered sects is the identification of Vishnu or Narayana as the one supreme God. This belief contrasts with the Krishna-centered traditions, such as Vallabha Sampradaya and Gaudiya Vaishnavas, in which Krishna is considered to be the supreme god and the source of all avataras. The belief in the supremacy of Vishnu is based upon the many avataras (incarnations) of Vishnu listed in the Puranic texts, which differs from other Hindu deities such as Ganesha, Surya or Durga. The latter are instead classified as demi-gods or devas. Vaishnavites consider Shiva, one of the Hindu Trimurti (Trinity) as subservient to Vishnu, and a Vaishnava himself. Swaminarayan, founder of the Swaminarayan faith, differs with this view and holds that Vishnu and Shiva are different aspects of the same God. Notably, the Swaminarayan view is a minority view among Vaishnavites.A few Vaishnava schools also identify the God of the Abrahamic religions with Vishnu; this is problematic in instances where YHWH/Allah is viewed as a single eternal being, outside, beyond and separate from his creation. Vishnu is viewed through
