The Motto of Indian Air Force is Nabha sparsham Deeptam. It has been taken from eleventh chapter of the Gita, the Discourse given by Lord Krishna to Arjunaon the battlefield of Kurukshetra during the Great War of Mahabharata. The Lord is showing His Supreme Divine form to Arjuna and the great form of the Lord is reaching the sky with glory, evoking fear and loss of self-control in the mind of Arjuna.
