A muscle is developed by taking physical exercise. Meditation is an inner exercise; if you practise regularly, its power increases. When you take physical exercise daily, even if for only five minutes, you strengthen your muscles. Then, after a few months you can take exercise for half an hour, an hour or two hours at a time. Similarly, if you meditate soulfully each day, then there comes a time when you make progress.
It is not how many hours you meditate but how you meditate. If you can meditate soulfully and devotedly for fifteen minutes and sincerely cry for Peace, Light and Bliss, that is better than three hours of meditation without any life in it. When you meditate, if there is a living presence in it, then that is meditation. Otherwise it is no better than sleep or death.
But if you say, "No, I want to have the highest meditation so that in this incarnation I can realise God," then I wish to say that you have to spend quite a few hours each day in meditation. Five, ten or fifteen minutes of meditation will not do. No, you have to spend quite a few hours in the highest form of meditation if your goal is to realise the Highest.From:Sri Chinmoy,Meditation: humanity's race and Divinity's Grace, part 1, Agni Press, 1974
