Pashupata Shaivism was a devotional (
bhakti) and ascetic movement. Pashu in
Pashupati refers to the effect (or created world), the word designates that which is dependent on something ulterior. Whereas, Pati means the cause (or principium), the word designates the Lord, who is the cause of the universe, the pati, or the ruler. To free themselves from worldly fetters Pashupatas are instructed to do a
pashupata vrata. Atharvasiras Upanishsad describes the pashupata vrata as that which consists of besmearing one's own body with ashes and at the same time muttering
mantra — "Agni is ashes, Vayu is ashes, Sky is ashes, all this is ashes, the mind, these eyes are ashes." Haradattacharya, in
Gaṇakārikā, explains that a spiritual teacher is one who knows the eight
pentads and the three functions. The eight pentads of Acquisition (result of expedience), Impurity (evil in soul), Expedient (means of purification), Locality (aids to increase knowledge), Perseverance (endurance in pentads), Purification (putting away impurities), Initiation and Powers are — The three functions correspond to the means of earning daily food — mendicancy, living upon alms, and living upon what chance supplies. ==Philosophy==
