Thai Buddhist monk Ajahn Chah quoted in Buddhist teacher Jack Kornfield’s Living Dharma: Teachings and Meditation Instructions from Twelve Theravada Masters (2010):

The Dharma of the Buddha is not to be found in books. If you want to really see for yourself what the Buddha was talking about you don’t need to bother with books. Watch your own mind. Examine to see how feelings come and go, how thoughts come and go. Don’t be attached to anything, just be mindful of whatever is there is to see. This is the way to the truths of the Buddha. Be natural. Everything you do in your life here is a chance to practice. It is all Dharma. When you do your chores try to be mindful. If you are emptying a spittoon or cleaning a toilet don’t feel you are doing it as a favor for anyone else. There is Dharma in emptying spittoons. Don’t feel you are practicing only when sitting cross-legged. Some of you have complained that three is not enough time to meditate. Is there enough time to breathe? This is your meditation: mindfulness, naturalness in whatever you do.
