then one can spend 12 hours for recitation of one's idol. Therefore, the
maximmum number of times that one can recite "mantra", or perform "Jap" are
10800. If one wants to obtain 100% benefit of its jap, then performing
jap 108 times will give you the benefit of 100%. That's why in a "Mala",

1 mala (which has 108 beads), therefore performing jap of 108 malas will
result in 100% benefit.
