You may go on reading any number of books on Meditation. They can only tell you ‘Realize the Self’. The Self cannot be found in books. You have to find it for yourself in yourself.
Nearly all mankind is more or less unhappy because nearly all do not know the true Self. Real happiness abides in Self-knowledge alone. All else is fleeting. To know one’s Self is to be blissful always.
Meditation is sticking to one thought. That single thought keeps away other thoughts; distraction of mind is a sign of its weakness; by constant meditation it gains strength.
