Choose one meditation and then put all your effort in it. That effort has to be very regular because will is created only out of regularity. It has to be very persistent and a continuity has to be maintained. Even to miss for one day is to destroy much - and at least one hour every day has to be given to it.
Remember always that the ultimate value is meditation, so anything you do, do meditatively; and all things can be done in a meditative way.
[M]ental peace is not meditation. Meditation is the flight beyond the mind. It has nothing to do with mental peace.
To me the greatest problem with humanity is that they don't know anything of meditation.
