The True Man
Yuga (Sanskrit: युग) means “a yoke” (joining of two things), “generations”, or “a period of time” such as an age, where its archaic spelling is yug, with other forms of yugam, yugānāṃ, and yuge, derived from yuj (Sanskrit: युज्, lit. ‘to join or yoke’), believed derived from *yeug- (Proto-Indo-European: lit. ‘to join or unite’).
In the Latin language, juga or jug is used from the word jugum, which means “a yoke used to connect two oxen” (e.g. cali-juga = kali-yuga).

Derived from buddhadhatu (Sanskrit), which means “essence of the Buddha,” from बुद्ध buddha, “conscious, awakened” and धातु dhatu, “element, primary element, cause, mineral.” The term buddhadhatu appeared in Mahayana scripture as a reference to tathagatagarbha, the “embryo of the Buddha,” also called Buddha Nature. In general use, this describes that element in us that has the potential to become a Buddha, an “awakened one.”
