The Sanskrit word kṛṣṇa means "black", "dark" or "dark-blue"[5] and is used as a name to describe someone with dark skin. Krishna is often depicted in murtis (images) as black, and is generally shown in paintings with a blue skin.Some Hindu traditions often ascribe varying interpretations and powers to the names. The Mahabharata's Udyoga-parva (Mbh 5.71.4) divides kṛṣṇa into elements kṛṣ and ṇa, kṛṣ (a verbal root meaning "to plough, drag") being taken as expressing bhū "being; earth" and ṇa being taken as expressing nirvṛti "bliss". In the Brahmasambandha mantra of the Vallabha sampradaya, the syllables of the name Krishna are assigned the power to destroy sin relating to material, self and divine causes.[6] Mahabharata verse 5.71.4 is also quoted in Chaitanya Charitamrita and Prabhupada in his commentary, translates the bhū as "attractive existence", thus Krishna is also interpreted as meaning "all-attractive one".[7][8] This quality of Krishna is stated in the atmarama verse of Bhagavatam 1.7.10.[9]
The name Krishna is also the 57th name in the Vishnu Sahasranama and means the Existence of Bliss, according to Adi Sankara's interpretation. [10] Krishna is also known by various other names, epithets and titles, which reflect his many associations and attributes. Among the most common names are Govinda, "finder of cows", or Gopala, "protector of cows", which refer to Krishna's childhood in Vraja.[11][12] Some of the distinct names may be regionally important; for instance, Jagannatha (literally "Lord of the Universe"), a popular deity of Puri in eastern India.[13]

established by 11th century AD. From the 10th century AD, with the growing Bhakti movement, Krishna became a favorite subject in performing arts and regional traditions of devotion developed for forms of Krishna such as Jagannatha in Orissa, Vithoba in Maharashtra and Shrinathji in Rajasthan. Since 1966, the Krishna-bhakti movement has spread in the West, with the International Society for Krishna Consciousness (ISKCON). Devotion to Krishna is widely diffused and extends to Jains, Buddhists, Bahá'ís and beyond India.
