dine dine ca saṃmṛṣṭaṃ saṃmārjanyā viśeṣataḥ |
vāsitaṃ ca sugandhena dhūpitaṃ guggulādibhiḥ ||

Mahāmuḍrā, Mahābanḍha and Khecharī, Jālanḍhara, Uddiyāṇa, and Mūlabanḍha, uttering without intermission Praṇava (Om) for a long time, and hearing the exposition of the supreme truths, Vajrolī, Amarolī and Sahajolī, which form a triad—all these separately I shall give a true description of. O four-faced one (Brahma), among (the duties of) yama moderate eating—and not others—forms the principal factor; and non-injury is most important in niyama. (The chief postures are) four (viz.,) Siḍḍha, Paḍma, Simha and Bhaḍra. During the early stages of practice, the following obstacles take place, O four-faced one, (viz.,) laziness, idle talk, association with bad characters, acquisition of manṭras, etc., playing with metals (alchemy) and woman, etc., and mirage. A wise man having found out these should abandon them by the force of his virtues. Then assuming Paḍma posture, he should practise prāṇāyāma. He should erect a beautiful monastery with a very small opening and with no crevices. It should be well pasted with cow-dung or with white cement. It should be carefully freed from bugs, mosquitoes and lice. It should be swept well every day with a broom. It should be perfumed with good odours; and fragrant resins should burn in it. Having taken his seat neither too high nor too low on a cloth, deerskin and kuśa grass spread, one over the other, the wise man should assume the Paḍma posture and keeping his body erect and his hands folded in respect, should salute his tutelary deity.
