Structure of Pranava OM – Shiva Purana

In the chapter 1 to 3 in Section 5 of Kailash-saṃhita of Shiva Purana, Shiva informed about Pranava to Parvati.

The Pranava is Shiva. Vedas arise from the Pranava. Pranava is the seed of all the lore. It is the imperishable Brahman, the means of attaining all objects. Shiva creates universe at the outset saying “Om”. He who aspires for salvation and is free from aberration shall understand Pranava as the cause of all and me as the Nirguṇa Parameshvara.

Structure of Pranava:
The Pranava of five syllables is explained by extricating the three Matras AUM), Bindu and Nada. It yields liberation to those who perform the Japa in this manner. Pranava is the vital breath of all living beings from Brahma to immobile beings. Being the Prana thus, it is called Pranava.

The first letter (A) is like water in the south, the second letter (U) is in the north; the letter M is like fire in the middle, before Nada and Bindu. ‘A’ is the great Bija, Rajas, the four-faced creator. ‘U’ is the Prakirti, source, Sattva, the protector Vishnu. ‘M’ is the Purusha, the Bijin, Tamas, the annihilator Shiva. Bindu is Maheshvara the lord, the disappearance. Nada is Sadashiva the bestower of blessings on all. On the top of Nada there is Shiva who is greater than the greatest. He is omniscient, the creator, the lord, free from dirt, the imperishable, the inexpressible, the great Brahman, beyond the existent and the nonexistent.

The five Brahmans beginning with Sadya and ending with Ishana are stationed in the five letters ‘A’ etc. They are my very forms in order. In the syllable ‘A’ eight Kalas of the form of Sadya exist. “In ‘U’ thirteen Kalas of the form of Vama exist. The eight Kalas of the form of Aghora are stationed in ‘M’. In Bindu four Kalas of the form of Puruṣa exist. In Nada five Kalas born of Ishana are present. Thus, their state of being the soul of the universe is due to the recognition of their sixfold identity.

The sixfold objects constitute Mantra, Yantra, deity, universe, the preceptor and the disciple. The mantra previously mentioned is a composite of five letters. The same attains the form of a Yantra. I shall mention the details of its mystic diagram. Yantra is in the form of the deity; the deity is in the form of the universe; the preceptor too is in the form of the universe and the disciple is of the body of the preceptor.
Om is everything, everything is Brahman. This Vedic Text establishes the link between the word and its meaning. The preceptor shall be one who has understood the tenets and the meanings of sacred texts; who has mastered Vedanta; who is an ascetic and the most excellent of intelligent men. After approaching him the intelligent brahmin shall prostrate before him and propitiate him by reverential deeds. That disciple is the most excellent who possesses good behavior and the qualities of peaceful calmness. The disciple shall realize that preceptor is Shiva and Shiva is the preceptor. Then he shall reveal his thought.

Holy rites by Preceptor:
After being permitted by the preceptor the brahmin devotee shall perform holy rites without taking anything except milk, for twelve days on the sea-shore, or on the banks of a river, or on a mountain or in a temple of Shiva. On the fifth or the eleventh day of the bright half he shall take his bath early in the morning. The intelligent devotee pure in mind shall perform his daily duty. He shall invite the preceptor duly and perform Nandi shraddha. He shall get himself shaved of the hair on the head and the moustache and the beards. The hair in the armpit and the private parts must not be shaved. The nails shall be cut. He shall perform his ceremonial ablution with restrained mind. He shall cat only powdered fried grain. In the evening he shall take his bath and perform Sandhya. In the presence of the preceptor, he shall perform the Aupasana rites in the evening. To Shiva in the form of the preceptor he shall give Dakṣiṇa according to the scriptures. He shall collect articles for Homa. place the holy fires, laukika and others, with the rules of his Gṛhya Sutra. A brahmin who consecrates the sacred fire shall perform this Aupasana in the sacrificial fire consecrated by the Prajapatya sacrifice, reciting mantras from the Vedas and offering due Dakṣiṇas. Then the brahmin shall superimpose the fire in the Atman and formally renounce the world. The food-offering shall be cooked with the fire-wood and cooked rice and ghee. He shall perform the sacrifice repeating the Purusha Sukta. The ghee shall be offered at the end of every stanza. The Sauvisṭakrti shall be performed in accordance with the rules of his own Sutra. After the sacrifice he shall perform Tantric activities. The learned devotee shall sit on a doth, deer-skin or Kusha grass to the north of the fire. He shall repeat the Gayatri mantra silently till the Brahma Muhurta, and stabilise his mind firmly. Then he shall take bath and cook the Caru. He shall perform the sacrifice beginning with Puruṣa and ending with the Viraja suktas. After performing the remaining rites of the sacrifice, he shall perform the Aupasana rites of the morning. Then he shall superimpose Agni in the Atman and perform the morning prayers. When the sun has arisen, he shall recite Savitri. He shall eschew the three Aṣaṇas and repeat the Presa mantras.

He shall abandon the tuft, the sacred thread and the girdle too. He shall start to the east or to the north. He shall lake with him a staff and a loin-cloth and such other things as are necessary for life. If he is totally detached, he need not take these things too. He shall approach the preceptor and prostrate before him thrice. Standing up he shall sit at the feet of the preceptor. The teacher shall take the white ashes from the Viraja fire and smear it over the body of the disciple. Repeating the mantra “Agniriti” etc. he shall make the three marks Tripuṇḍra on his forehead. He shall think of me stationed in the lotus of the heart along with you. Then the teacher shall place his hand on the head of the disciple. With a delighted mind, the preceptor shall utter the Pranavamantra thrice in the right ear of the disciple mentioning the sage etc. Then he shall tell him the sixfold meaning. The disciple shall bow prostrate before the preceptor on the ground twelve times. He shall remain subservient to him and practise the study of the Vedanta strenuously. He shall ponder and meditate in the pure Atman without aberrations, upon me the great Atman, the Saksin of Brahman, the unchanging.

Here the person authorised is the ascetic engaged in the pious activities of self-restraint, the master of Vedantic knowledge and free from rivalry. The lotus of the heart is free from dust, devoid of sorrow, clear and great. It has eight petals with filaments and it shines above the pericarp. After thinking about the region from the Adhara-Shakti to the three Tattvas the Dahara Vyoman (the ether-heart) shall be imagined and conceived in the middle. Repeating the single-syllabled Brahman Om, he shall with alert mind think of me along with you in the middle.

​He who performs the rite of this type attains my world. After securing the knowledge of my principles he will attain Sayujya salvation as the fruit.
