प्राणायामेन संयम्य मनो वर्षशतं मुनिः ।
अतिष्ठदेकपादेन निर्द्वन्द्वो ऽनिलभोजनः ॥ १९ ॥
nirdvandvo 'nila-bhojanah
pranayamena-by practice of the breathing exercise; samyamya-controlling; manah-mind; varsa-satam-one hundred years; munih-the great sage; atisthat-remained there; ekapadena-standing on one leg; nirdvandvah-without duality; anila-air; bhojanah-eating.
There the great sage concentrated his mind by the yoga breathing exercises, and thereby controlling all attachment, he remained standing on one leg only, eating nothing but air, and stood there on one leg for one hundred years.
