Each hair-tip (as described above) is cut into a number of pieces equivalent to the number of samayas in uncountable crore years and the cylindrical vessel or pit is made cram-full with these hair-pieces. Every samaya, a single piece is removed from it. The total period of time that elapses for emptying it completely is called uddhāra palyopama. In this way-
1 uddhāra palyopama = (4.13 x 1044) x (number of samayas in uncountable crore years) samayas
If the number of samayas in one year be a1, and uncountable years be a2, then
1 uddhāra palyopama = (4.13 x 1044 x a1 x a2 x 107) samayas, but a1 = one year.
So,
1 uddhāra palyopama = (4.13 x 1044 x 107 x a2) years
= (105 x a2) vyavahāra palyopamas.
