The phallic emblem confers enjoyment it is the only means of worldly enjoyment and salvation. Viewed, touched or meditated upon, it wards of all future births of the living beings.
The Isatva in me is to be known as the embodied form and this symbolic column (Linga) is indicative of my Brahmatva.
The phallic symbol and the symbolized Siva are none-different. Hence this phallic emblem is identical with me. It brings devotees quite near to me. It is worthy of worship therefore.
O dear sons, if the phallic emblem of this sort is installed I can be considered installed, though my idol is not installed.
The installation of the phallic emblem is primary and that of the embodied idol is secondary. A temple with the embodied idol of Siva is infructuous if it has no phallic image.
Although I consider the phallic and the embodied form to be equal, the phallic form is excellent for those who worship. Hence for those who seek salvation the latter is preferable to the former.
When I am worshipped in the phallic form I will be delighted and will bestow different benefits upon all people, all that they wish for in their minds.
O foremost among the deities, whenever any misery befalls you, it shall be destroyed when my linga is worshipped.
The devotee shall use Sami flower, Bilva leaves and lotuses duly. He can use other flowers also but he shall not abandon the Bilva leaf.
The devotee bathes my linga at the outset with cow's ghee. The he consecrates it with the other materials. Thereafter he washes it with water.
He shall circumambulate the excellent Linga and prays thus:
"O lord of Devas, O Sankara it behoves you to forgive all my sins. Forgive me if my worship is devoid of the requisite materials faith and rites.
The great goddess (Parvati) is the altar (pedestal) for the Linga. The Linga is the great Lord (Siva) himself.
Linga is so called because, O gods everything gets dissolved in it.
Important Note: The Twelve Jyotirlingas. Lord Siva manifested of his own accord in Linga form in many places. Among these, there are twelve Jyotirlingas, which are the most prominent and glorious pilgrim centers of India.
