Pasupata Toga1 - Verse 13-18

One should utter the syllable Om at the outset and bow to the moon or the sun. Then he should sit in the postures of Svastika or Ardhapadma. The two knees shall be level with each other or one knee should be slightly raised. He should sit comfortably with firmness. The feet shall be brought closer. The mouth should be kept closed, the eyes half-closed, the chest raised forward. With the heels he should cover the scrotum and the penis ; the head should be slightly raised, the neck be straightened. He should fix his gaze on the tip of his nose, and should not look elsewhere in any direction. He should cover Tamas by Rajas which he should envelop by Sattva. Then he should remain established in Sattva and practise Yoga with pure mind. He should then hold (control ) the aggregate of his sense-organs and their objects, his mind and the five vital breaths. He shall then begin Pratyahara (withdrawing in himself these together) .
