According to the ancient teachings, the aspirant, faithful to their own spiritual order, begins a gradual process of inner purification. This is done by discerning and refining the qualities within, whether they are manifest, hidden, or yet to be revealed. Through this process, the seeker cuts through the subtle centers—beginning with the heart, then the throat, the palate, the brow center, and finally the crown of the head. Encompassing the eightfold form of the self, they guide their consciousness upward through the central channel. When the seeker’s awareness reaches the region twelve finger-widths above the head, known as the seat of the moon, they are to merge this subtle essence into the radiant light of Shiva. Here, the power of speech is dissolved and absorbed, as prescribed by the tradition. The body, now sanctified by the nectarous shower of Shakti, is again infused as the immortal self is brought gently down and established in the heart. Beyond that lunar sphere, in the pure white lotus above, the devotee beholds Mahadeva—Shankara, the compassionate Lord, ever affectionate to his devotees. It is here that the seeker contemplates Ardhanarishvara, the God who is both Shiva and Shakti, whose form is pure, sweet, serene, and radiant like a flawless crystal, exuding a cool, soothing light. With a tranquil mind, the devotee meditates upon this divine form and worships with heartfelt devotion, offering the eightfold name of Shiva as flowers of love. After this worship, the breath is controlled and the mind properly centered; then, the sacred eightfold Shaiva name is recited with reverence. Eight oblations are offered into the subtle navel fire, followed by a complete offering, and the final worship is rendered with eight flowers. The devotee then dedicates themselves with the ritual water from the ladle, and, after a period of steadfast practice, attains the auspicious Pāśupata knowledge. With this realization comes the establishment in the highest conduct and the supreme yoga, and, having attained these, the seeker is liberated—there can be no doubt. At this point, the sages address the Lord: “O Lord, we wish to hear about the supreme Pāśupata vow, which, when performed by Brahmā and others, made them renowned as Pāśupatas.” The Lord replies: “I shall reveal to you the secret of the Pāśupata vow, as taught in the Atharvaśiras scripture—a vow which destroys all sins. The appropriate time for this vow is the full moon of the month of Caitra, and the place should be a field, garden, or forest dedicated to Śiva, one that is praised and marked by auspicious signs. On the thirteenth day, after bathing thoroughly and performing the virtuous daily rites, the aspirant should seek permission from their teacher, worship him, and bow down in respect. After performing the special worship, the seeker dresses in white garments, dons a white sacred thread, and adorns themselves with white garlands and fragrant ointments. Seated upon a mat of darbha grass, holding a fistful of the sacred grass, and facing east or north, the aspirant performs the threefold breath-control and meditates upon the God and Goddess, invoking them according to the prescribed method. With a firm resolve—'I undertake this vow'—the seeker is initiated, whether for the duration of their life, for twelve years, or for half that time, or again for half of that, or for twelve months, half of that, or half again, or for one month, twelve days, six days, three days, or even just one day. Thus, the duration of the vow is determined. The sacred fire is then established according to the rules for a spotless homa. The aspirant offers oblations of ghee, sticks, and cooked food in the prescribed order. Filling the vessel anew for the purification of the principles, offerings are made with the root mantra, using the same sacred materials. The aspirant contemplates the five elements, their subtle forms, and the five organs of action; distinguishes between knowledge and action, the five divisions of action, the seven bodily substances beginning with skin, and the five vital airs. Mind, intellect, ego, discernment, the qualities, nature and spirit, attachment, knowledge, the powers, order, and time are all included in this contemplation. Māyā and pure knowledge, Maheśvara and Sadāśiva, power and the principle of Śiva—these are known in their succession. By offering these oblations with pure mantras, the sacrificer is purified and, by Shiva’s grace, becomes truly wise. Then, taking cow dung, forming it into a lump, consecrating it with mantras and placing it in the fire, the aspirant sprinkles it and partakes of the sacrificial food that day. On the morning of the fourteenth day, after completing all previous rites, the aspirant observes a fast for the remaining prescribed time. At the sacred juncture of dawn, the homa is performed as before, and the ashes of the Rudra-fire are carefully collected. After bathing, the aspirant may become matted-haired, shaven-headed, or wear a single topknot. Standing unashamed, clad only in the directions, or else in ochre garments, a hide, a single cloth, or bark, and carrying a staff and girdle, the aspirant washes their feet and, sitting again, unites their body and carefully applies the pure ash from the sacred fire. With the six Atharvan mantras beginning with ‘Agni’, the aspirant anoints their limbs in order, from head to feet. Then, taking up the ash, they sprinkle it over the whole body, with the syllable Om or the name of Shiva. The three sacred lines called 'triyāyuṣa' are then marked, and the aspirant attains the state of Shiva, practicing the yoga of Shiva. The three daily sandhyās are also performed. This is the Pāśupata vow, which bestows both enjoyment and liberation and removes the bonds of worldly existence. Having cast off bondage and undertaken the Pāśupata vow, the eternal Mahādeva, in the form of the liṅga, is to be worshipped. For this worship, the aspirant prepares a seat in the form of an eight-petaled golden lotus, adorned with nine gems and furnished with a central filament. If such means are not available, a red or white lotus may be used, or, if that too is not possible, a seat made only in contemplation is sufficient. Thus, the path to the supreme Pāśupata vow and worship is laid out, leading the devoted seeker step by step toward liberation and union with the gracious Lord Shiva.
