There is an Unaalome (ever decreasing spiral) at each end of a Yant to complete it.
The spiral indicates the earthly distractions we encounter in our daily lives and as we grow older and wiser, this spiral gradually decreases until it becomes a straight line pointing upwards.
This signifies the path to Nirvana or true enlightenmen.
The signification and history of unalome symbol, is still mysterious to this day.
Unalomes are spiritual symbols and close to other spiritual symbols
( Buddist Sanskrit and Tibetan).
The common signification is that they represent the path to enlightenment.
Unalome tattoos have been growing in popularity.
