Shiva Drishti in Hindu religion is the blessing with Shiva’s benevolence or being blessed by it. Shiva means truthful, everlasting and beautiful. Shivadrishti results in immense happiness and is expressed as ananda. Brahmastura declares Brahman as satyam (true), Shivam (auspicious) and sundaram (beautiful). Shiva has been discussed at length in Brahmasutra as a bestower of mangala (auspiciousness).
The two eyes of Shiva are meant for blessing. The third eye is opened only during pralaya (delugue) for samhara (destruction). Nityananda, who is the foremost amongst the devotees, was blessed by Shivadrishti. Sometimes Chaitanyawould make him dance. Sometimes he danced along with Shiva, lost in the ecstasy of spiritual love.
Sivadrishti blesses devotees, and the third eye of Shiva destroys enemies and opponents. Legend has it that Kamadeva endeavored to motivate Shiva to marry Parvati while he was doing a penance, but was destroyed by the third eye of Shiva. This is a Puranic episode indicating the anger of Rudra. There are similar instances of Shiva using his third eye whenever he is opposed or contradicted. In the story of Nakkiran (a poet in the court of a Pandya king in South India), Shiva opened his third eye to reduce him to ashes, since the poet had criticized his composition as incorrect.
Nataraja blessed Kannappa, a staunch devotee, with new vision, when he had sacrificed his eyes for him. Shivadrishti, in this context, may be called the auspicious outcome of Shiva’s benevolence.
