[paragraph continues] Its practice and melana 1 are not accomplished simultaneously. Those that are bent upon practice alone do not get melana. Only some get the practice, O Brahman, after several births, but melana is not obtained even after a hundred births. Having undergone the practice after several births, some (solitary) yogin gets the melana in some future birth as the result of his practice. When a yogin gets this melana from the mouth of his guru, then he obtains the siḍḍhis mentioned in the several books. When a man gets this melana through books and the significance, then he attains the state of Śiva freed from all rebirth. Even gurus may not be able to know this without books. Therefore this science is very difficult to master. An ascetic should wander over the earth so long as he fails to get this science, and when this science is obtained, then he has got the siḍḍhi in his hand (viz., mastered the psychical powers). Therefore one should regard as Achyuṭa (Vishṇu) the person who imparts the melana, as also him who gives out the science. He should regard as Śiva him who teaches the practice. Having got this science from me, you should not reveal it to others. Therefore one who knows this should protect it with all his efforts (viz., should never give it out except to persons who deserve it). O Brahman, one should go to the place where lives the guru, who is able to teach the divine yoga and there learn from him the science khecharī, and being then taught well by him, should at first practise it carefully. By means of this science, a person will attain the siḍḍhi of khecharī. Joining with khecharī śakṭi (viz., kunḍalinī śakṭi) by means of the (science) of khecharī which contains the bīja (seed of letter) of khecharī, one becomes the lord of khecharas (Ḍevas) and lives always amongst them. Khecharī bīja (seed-letter) is spoken of as agni encircled with water and as the abode of khecharas (Ḍevas). Through this yoga, siḍḍhi is mastered. The ninth (bīja) letter of somāmśa (soma or moon part) should also be pronounced in the reverse order. Then a letter composed of three amśas of the form of moon has been described; and after that, the eighth letter should be pronounced in
