what's the song at the beginning of class?

Patanjali Chant

yogena cittasya padena vacam

yo-gay-na chi-tah-sya pa-day-na va-cham

malam sarirasya ca vaidyakena

ma-lam sha-ree-ra-sya cha vy-dyu-kay-na

yopakarottam pravaram muninum

yo-pa ka-ro-tam pra-va-ram moo-nee-nam

patanjalim pranjaliranato 'smi

pa-tan-ja-lim pran-ja-leer ah-na-to-smi

abahu purusakaram

ah-ba-hoo pu-ru-sha-kar-ahm

sanka cakrasi dharinam

shan-ka cha-kra-see dar-ee-nam

sahasra sirasam svetam

sa-ha-sra sheer-ah-sam shvay-tam

pranamami patanjalim

pra-na-ma-me pa-tan-ja-lim
