Ashtanga Opening Mantra

Om
vande gurunam caranaravinde
sandarsita svatma sukhava bodhe
nihsreyase jangali kayamane
samsara halahala moha santyai

abahupurusakaram
sankha cakrasi dharinam
sahasra sirasam svetam
pranamami patanjalim
Om

Om
I pray to the lotus feet of the supreme guru
Who teaches knowledge, awakening the great happiness of the self-revealed
Who acts like the jungle physician
Able to remove the delusion from the poison of conditioned existence

To Patanjali, an incarnation of Adisesa, whit in colour with a thousand radiant heads (in his form as the divine serpent, Ananta), human in form below the shoulders, holding the sword of discrimination, a wheel of fire representing infinite time, and the conch representing divine sound to him, I prostrate.

May divinity and erudition be protected
And may all people of this world be happy and free
