Palya
A palya is a length of time used in Jainism to describe when the Lord Adinath ("First Lord") came to India, 100,000,000,000,000 palyas ago. A palya is defined as the time it takes to build a cube of lambswool 1 (or possibly 100) yojans high (between 4 and 9 miles or 6.4 km and 14.5 km), if one strand was laid down every century.
