Tulsi or Tulasi (Ocimum tenuiflorum) or Holy basil is a sacred plant in Hindu belief. Hindus regard it as an earthly manifestation of the goddess Tulsi, a consort of the god Vishnu. The offering of its leaves is mandatory in ritualistic worship of Vishnu and his forms like Krishna and Vithoba.
Many Hindus have tulsi plants growing in front of or near their home, often in special pots or special small masonry structures. Traditionally, Tulsi is planted in the center of the central courtyard of Hindu houses.The plant is cultivated for religious and medicinal purposes, and for its essential oil.
While tree worship is not uncommon in Hinduism, the Tulsi plant is regarded the holiest of all plants.The Tulsi plant is regarded as a threshold point between heaven and earth. A traditional prayer tells that the creator-god Brahma resides in its branches, all Hindu pilgrimage centres reside in its roots, the Ganges flows through its roots, all deities in its stem and its leaves and the Hindu scriptures – the Vedas in the upper part of its branches. It is considered as household god particularly referred as a “Women’s deity”. It is called as “the central sectarian symbol of Hinduism” and Vaishavas consider it as “the manifestation of god in the vegetable kingdom”.
