spirituality is essentially a cleaning process for human

as if it is a metallurgy, from raw ore, to pig iron, to steel, to steel parts,

as if it is derusting, degreasing, polishing, honing,

and render the mind body absolutely in the fittest possible condition

for the best usage

so maintain it by schedule, routine, daily weekly, monthly cleaning processes

with all kinds of appropriate spiritual techniques and processes, including pooja, vratha, fasting,
