Mind allures you to expect the unexpected and again denies which is almost certain to occur. It exaggerates the trivial. The prominent is declared void. This is the mechanism to take your control making you deceptive leading to delusion.
Meditation is the methodology which makes you take control of mind under your command. And then conserve the dissipation of energy.
Meditation is ill-conceived to be a tiring job. Yes it is if you are a very complex character and playful and romantic if an easy going person.
Meditation basically is to be thoughtless at will to give way to a streamlined process. The objective can be easily approached and achieved if you agree to be a spectator, an observant as if you are a testimony of the happenings inward.
N.B. 1. Meditation is not the concentration.
2. Science is an objective while Spiritualism is a subjective approach.
