Dakshinamurthy or Jnana Dakshinamurti (Kannada:ದಕ್ಷಿಣಾಮೂರ್ತಿ, Tamil: தட்சிணாமூர்த்தி, Sanskrit: दक्षिणामूर्ति (Dakṣiṇāmūrti)) is an aspect of the Hindu god Shiva as a guru (teacher) of all types of knowledge (jnana). This aspect of Shiva is his personification as the supreme or the ultimate awareness, understanding and knowledge. This form represents Shiva as a teacher of yoga, music, and wisdom, and giving exposition on the shastras. He is worshipped as the god of wisdom, complete and rewarding meditation. As per scriptures,if a person doesn't have a Guru, then they can consider and worship Lord Dakshinamurthy as their Guru.Eventually they will be blessed with a human Self-Realised Guru, if they are worthy.
Meaning
Dakshinamurti literally means 'one who is facing south (dakṣiṇa)' in Sanskrit. South is the direction of Death, hence change. In every Siva temple the stone image of Dakshinamurthy is installed, facing south, on the southern circumambulatory path around the sanctum sanctorum. Perhaps, of all Hindu Gods, he is the only one sitting facing south. The great seer Ramana Maharshi, has said in letter 89:
one meaning of Dakshina is efficient; another meaning is ‘in the heart on the right side of the body’; Amurthy ’means Formlessness' .
"Dakshinamurthy Stotra" in Sanskrit, means the "Shapelessness situated on the right side".
