Hi Ernst,
Ayanamsas are supposed to be a basic and foundational astronomical aspect to astrology that shows the difference in degrees of the tropical vernal equinox and sidereal zodiac. Yet, I see varying definitions of Ayanamsa. Ayana means 'going', sometimes 'movement'. Brihat Samhita says ayana is '6 months'. Amsa means 'parts', sometimes I see it translated as 'components'.
Can you give a straight forward definition of 'Ayanamsa' and what exactly is an Ayanamsa?

Ernst can answer more in depth but I found it helpful to learn this: a more common way ayana is translated is as "a time pass" as they say in india. So one might say "I worked for a year as a cook, just as a "time pass". Like as in something to do for awhile. Ayana means a time pass, or a a journey, a thing you do that takes up time.
So ayanamsha like many sanskrit words has multiple levels of meaning, and it can mean the division of time taken away to arrive at something. I think thats one way to grasp what it means in the jyotish context.
And so for example the Ramayana is translated as "Ram's journey" but it also can be playfully seen as "Ram's timepass" since Ram was Vishnu, who incarnates every so often out of love for his devotees, and perhaps as a way to pass the time 😉
