Someone asked :
Can meditation be bad for you?
The answer is short, simple and plain :
Never if you do it properly.
May be, if you don’t do it correctly.
Yes, if you misunderstood it and treat it as a financial investment and expect return from it.
Expectations divert you from the goal.
Meditation is choiceless awareness. The lesser you expect, the greater will be your reward.
It is a game in contrast. Those who are ready to lose, they will conquer.
