The Art of Meditation Practice : หน้า 128/200

Keep practicing with the right method. If it takes you half an hour to get to the point of contentment, try to reach that same point each time. Your speed of getting there will improve as you go—from half an hour to 15 minutes, to 5 minutes, to 1 minute, to the very moment you close your eyes. When you arrive at that point your progress will step up. Your mind will become more refined, the time to get there will be shorter, and the images will emerge more often and more clearly. You’ll feel increasingly blissful each time a new inner image emerges (bright light, Dhamma spheres, inner bodies, inner Buddhas). Maintain this state of contentment as best as you can. When you get to this state of achievement, you’ll no longer feel bored, annoyed or agitated. Instead, you’ll find great joy every time you meditate. But if you feel unnatural, or have to use too much effort, it means you’re not doing it the right way. In which case, get up to wash your face, then come back again to restart. Remember the instruction given you. Follow the instruction full heartedly like a kindergarten student.
