Everything can be abused, even meditation. It’s been said soldiers are trained to meditate to make them feel fearless. The risk, however, is that capitalistic and egocentric meditation practices may backfire – you might instead wake up, understand yourself and others in a different light, and simply make you a better person, not materialistically richer, or a better soldier.
Give it a shot, worst case scenario – you become a billionaire! Best case scenario – you just become a better and sharper individual.
