AMSA
Amsa
Amsa, Amsu (Sanskrit) Fragment, particle, part; name of one of the adityas in the Mahabharata; also of Surya (the sun) whose solar energy was so tremendous that the divine architect Visvakarman cut off an eighth part of his glory. From the luminous fragments (amsa) which fell to earth, Visvakarman made a number of implements for the gods, including Vishnu's discus and Siva's trident. In the Bhagavad-Gita (15:7), Krishna emanates an amsa of himself which, becoming a jiva (monad) in the world of living beings, draws to itself manas (mind) and the five senses which originate in prakriti (nature).
Also, the tonic or predominant note in a raga, a Hindu mode of musical notes or melodic sounds so formulated as to arouse intensity of emotion, often of a high order, appropriate to the different portions of the day and night.
In theosophy amsa may be applied to particles of any kind: to a life-atom as well as to a monad as points or "fragments" of the cosmic consciousness-life-substance.
