Vishnuism consists of several directions that have developed divergent philosophies. These are handed down through various traditional schools, the Guru Sampradayas with numerous branches often perceived as separate Sampradayas. Most of today's teachings derive from one of these philosophers. In all of them, bhakti, loving devotion to Vishnu-Narayana, the avataras Krishna and Rama is central to their worship and teachings.
Sri Sampradaya and Ramanandi Sampradaya
→ Main article: Sri Vaishnava
The best known representative of the Sri-Sampradaya named after the goddess Sri Lakshmi is the philosopher Ramanuja (1017-1137). He taught vishisht-advaita, "qualified non-dualism", according to which "the all-one God Narayana is not an all-encompassing being, by itself devoid of all differences, but by nature already possesses the individual souls and the inanimate as qualities". Ramanuja represents the concept of a personal supreme being, Narayana. The unifying factor between the supreme being and the individual souls is divine love.
A branch that appears independently today is the Ramanandi Sampradaya. It traces its origin to Ramananda (13th century), who was a disciple in the line of Ramanuja, but later became independent. Ramananda placed Rama and Sita at the centre of religious worship. A large proportion of Vishnuit sadhus today are Ramanandis. The best known followers were Kabir (1440-1518), who founded his own school, and the later founder of Sikhism, Nanak. The Ramanandi Sampradaya itself has numerous sub-branches.
Brahma Sampradaya and Gaudiya Sampradaya
The best-known representatives of the Brahma-Sampradaya named after the god Brahma are Madhva (probably 13th century), also called Anandatirtha, as well as the mystic Chaitanya (1486-1533), who was mainly active in Bengal and whose lineage, the Gaudiya Sampradaya is a subgroup of the Brahma-Sampradaya. Madhva particularly emphasized dualism, dvaita, and strictly distinguished between God, the material world (prakriti), and souls. The goal was not to become one with the divine, as the followers of the Advaita doctrine, which he vehemently opposed, saw it, but bliss in Vaikuntha, Vishnu's "heaven", in the presence of the divine.
Chaitanya, on the other hand, emphasized both duality and the simultaneous unity of God, souls and the world. His philosophy is called acintya-bheda-abheda-tattva, the highest truth, God, being inconceivably simultaneously one (bheda) and yet distinct (abheda) from everything. The doctrine is provided with the addition acintya, i.e. "inconceivable", since it is not rationally comprehensible.
While Vishnuites in the sense of Madhva make up only a very small part, the many branches and twigs that emanated from Chaitanya's lineage are hardly manageable today. Outstanding is Bhaktisiddhanta Saraswati Thakura's Gaudiya-Math, from which the Hare Krishna movement known in the West emerged as a branch.
Rudra-Sampradaya
In the Rudra Sampradaya named after the god Shiva (Rudra), the best known exponent is Vallabha (1479-1531). He represents suddha advaita, "pure non-dualism". According to this, Krishna is identical with the supreme world-soul, Brahman, and includes the diversity of the world in himself. In his commentaries, Vallabha is particularly concerned to lead his followers to the "path of grace", pushiti marga.
Vallabha's teaching is said to be descended from Vishnu Swami (c. 13th century), an elderly master. He had taught advaita, pure non-duality.
Kumara-Sampradaya
After the four sons of the god Brahma, the Kumaras, the Kumara-Sampradaya, also Sanakadi-Sampradaya was named. The most important representative of this now less popular school is Nimbarka (probably 13th century). He established the philosophy of dvaita-advaita, simultaneous two-ness and non-two-ness: that God was simultaneously one and distinct from the world. According to this school, moksha, liberation, is attained through true knowledge, which in turn can be gained through true worship of God. For Nimbarka, unlike the other Vaishnuite doctrines, Krishna is not an avatar but the very essence of God and he, like Vallabha, identifies Krishna with Brahman. Nimbarka was known as a special devotee of the divine couple Radha and Krishna.
Reformed groups
In addition to the main sampradayas mentioned above, there are about twelve major reformed groups whose monks, the sadhus, sometimes engage in extraordinary practices, such as those of the Sakhi Sampradaya, who assume a female identity in their worship.
Followers of the Mahanubhoa Pantha completely reject the typical Hindu worship of the divine in effigy. Monks of the Harshachandi Pantha remain street sweepers even after their initiation, from whose caste they predominantly come.
The Kabira Pantha goes back to the poet and mystic Kabir. Kabir was initially a Muslim, but turned away from it early on. He also incorporated the teachings of Islamic mysticism, Sufism, into his philosophy. His songs are still popular throughout India.
The school of the spiritual teacher Swaminarayan, founded in the eighteenth century, is especially widespread in the Indian state of Gujarat. Members of this lineage, especially through emigrated Hindus, maintain temples and centers worldwide, such as the largest Hindu temple in Europe in London-Neasden.
