Kaviraj Gautam

“The sadhaka and sadhika are respectively the man or woman who perform sadhana. They are, according to their physical, mental, and moral qualities, divided into four classes – mridu, madhya, adhimatraka, and the highest adhimatrama, who is qualified (adhikari) for all forms of yoga. In a similar way the Kaula division of worshippers are divided into the prakriti, or common Kaula following virachara, addicted to ritual practice, and sadhana, with pancha-tattva; the madhyama-kaulika, or middling Kaula, accomplishing the same sadhana, but with a mind more turned towards meditation, knowledge, and samadhi; and the highest type of Kaula (kaulikottama), who, having surpassed all ritualism, meditates upon the Universal Self.”

“The yuga is a fraction of a kalpa, or day of Brahma of 4,320,000 human years.”

“It should be thirty-six fingers breadth (in circumference) in its widest part, and sixteen in height. The neck should be four fingers breadth, the mouth six fingers, and the bottom five fingers breadth. This is the rule for the design of the kalasha (182). It should be made either of gold, silver, copper, bell-metal, mud, stone, or glass, and without hole or crack.”
― Arthur Avalon, Mahanirvana Tantra

“The term pashu comes from the root pash, "to bind." The pashu is, in fact, the man who is bound by the bonds (pasha), of which the Kularnava Tantra enurnerates eight – namely, pity (daya), ignorance and delusion (moha), fear (bhaya), shame (lajja), disgust (ghrina), family (kula), custom (shila), and caste (varna).”
