"Ana is a mathmatical / philosophical term which can be best described as the 4th-dimensional equivalent to up in 3 dimensional geometry. Its opposite is kata. Ana and kata are like up and down, and can collectively be described as "the directions you can't point in". It's useful to define these when trying to visualise 4-dimensional geometrical shapes such as a hypersphere. Note that here, the 4th dimension simply refers to another geometrical dimension, not time."
Both words and concepts are Bharath - India - Sanskrit/Indian language origin. Ancient Bharath - Indian grammarian supreme - Panini described 2197 phonetic elements-(dhAtu)-of the words. Some wrongly call dhAtu - elements as "roots" - Nothing grows up from roots - roots and shoots of a plant are parts of one entity - one is found sub surface usually and other above surface - hence "root" is wrong usage for concept - element
Panini's dhAtu for the word is most likely
ah to pervade {ahna means pervading)
kat. {pronounced (cut + Ta in english)}to rain; to cover or to surround
The connotation derivable is - in a pervasive area (including the 3 dimensions - not excluding)

My conviction - "Time" - is figment of collective imagination of humankind - It has no physical reality. It is an arbitrary (collectively agreed unit of measure of human observed/observable events in the universe). However - I do not (as human) imply that this is not a convenient notion - That stick and shadow on the ground - or clock - are both arbitrary measures of not "Time" but observation of energy/matter events in space.
