Rudrayamala Tantra

Agama—These have become universally accepted as having "come from the mouth of Shiva, gone into the mouth of Girija, and been agreed upon by Vishnu." The recognition of Agamas as the primal and Arsha of the sages/divine texts is prevalent throughout the entire Tantric literature. Like the Vedic literature, the origin of the Agamas is also considered divine. If the Vedas are the breath of Brahma, then the Agamas have manifested from the breath of Lord Shiva:

"It is considered an Agama because it is understood to be a command for duty from all sides."

According to this Tantric definition, they are called "Agama" because they provide the object in the form of a command for duty from all directions. Although very little Agamic literature is currently available, the essence of what various scholars have published about it from different texts is as follows:

Agamic Literature—The Shaiva and Shakta Agamas are considered to have emerged from the five faces of Shiva. Ishana, Tatpurusha, Sadyojata, Vamadeva, and Aghora are these five faces of Shiva. From these faces, five powers—Siddha, Ananda, Iccha, Jnana, and Kriya—manifest respectively. The formation of the five faces of Sadashiva leads to the emergence of the states of difference (Bheda), difference-and-non-difference (Bhedabheda), and non-difference (Abheda). Maheshwara is considered to have 10 states dominated by difference, 18 by difference-and-non-difference, and 64 by non-difference. These very states give birth to Agamic literature.

Param-Shiva Himself attains the names of Shiva in the state of difference, Rudra in the state of difference-and-non-difference, and Bhairava in the state of non-difference. The Agamas associated with them are called "Shaivagama," "Rudragama," and "Bhairavagama" respectively.

Shaivagama—There are 10 Shaivagamas. It is said that after the creation of the world, God first created 10 Shivas and gave each of them a portion of His undivided great knowledge. The number and names of these original Shivagamas are as follows:

1. Kamikagama—The first name among the ten Shivas is Pranava Shiva. The Agama obtained by him from God is "Kamika." This Agama was obtained by Trikala from Pranava Shiva, and by Hara from Trikala. In both the "Kiranagama" and "Kamikagama," the name of the text is specified as "Kamika," but according to the Shrikanthasamhita cited by Jayaratha...
