However, I don't regret the time I've spent meditating as (knowing me) I would have squandered those hours anyway. Its often easy to forget the benefits of meditation and I sometimes question whether I should carry on. However, in common with others I have talked to, when I stop for a few days all the old thought patterns come back such as anger, fear, arrogance, sadness and desire for material gain. I still feel these things when I've been meditating but they don't control my actions and distort my thoughts nearly as much. Yeah, if I stop meditating it becomes obvious I should start again as soon as possible.
Meditation isn't for everybody. Only a small proportion of Westerners who try it actually carry on practicing long term. However, I'd recommend anyone thats curious to give meditation a go.
