Opening the Door to the Dhamma
Respect in Buddhist Thought & Practice
by Thanissaro Bhikkhu
If you're born into an Asian Buddhist family, the first thing your parents will teach you about Buddhism is not a philosophical tenet but a gesture of respect: how to place your hands in añjali, palm-to-palm over your heart, when you encounter a Buddha image, a monk, or a nun. Obviously, the gesture will be mechanical at first. Over time, though, you'll learn the respectful attitude that goes with it. If you're quick to pick it up, your parents will consider it a sign of intelligence, for respect is basic to any ability to learn.
As you get older, they may teach you the symbolism of the gesture: that your hands form a lotus bud, representing your heart, which you are holding out to be trained in how to become wise. Ultimately, as you grow more familiar with the fruits of Buddhist practice, your parents hope that your respect will turn into reverence and veneration. In this way, they give a quick answer to the old Western question of which side of Buddhism — the philosophy or the religion — comes first. In their eyes, the religious attitude of respect is needed for any philosophical understanding to grow. And as far as they're concerned, there's no conflict between the two. In fact, they're mutually reinforcing.
This stands in marked contrast to the typical Western attitude, which sees an essential discrepancy between Buddhism's religious and philosophical sides. The philosophy seems so rational, placing such a high value on self-reliance. The insight at the heart of the Buddha's awakening was so abstract — a principle of causality. There seems no inherent reason for a philosophy with such an abstract beginning to have produced a devotionalism intense enough to rival anything found in the theistic religions.
Yet if we look at what the Pali canon has to say about devotionalism — the attitude it expresses with the cluster of words, respect, deference, reverence, homage, and veneration — we find not only that its theory of respect is rooted in the central insight of the Buddha's awakening — the causal principle called this/that conditionality (idappaccayata) — but also that respect is required to learn and master this causal principle in the first place.

Especially interesting is the protocol of respect for the Dhamma. Buddhist monks and nuns are forbidden from teaching the Dhamma to anyone who shows disrespect, and the Buddha himself is said to have refused to teach his first sermon to the five brethren until they stopped treating him as a mere equal.
This protocol, of course, may have been a cultural accident, something picked up willy-nilly from the society of the Buddha's time, but there are passages in the canon suggesting otherwise. Buddhism was one of the samana (contemplative) movements in ancient India, which claimed to follow truths of nature rather than mainstream cultural norms. These movements were very free in choosing what to adopt from prevailing customs. Buddhist descriptions of other samana movements often criticized them for being disrespectful not only to outsiders but also among themselves. Students are shown being disrespectful to their teachers — their group meetings raucous, noisy, and out of control. All of this is then contrasted with the way Buddhists conduct their meetings in mutual courtesy and respect. This suggests that the Buddhists were free to reject the common customs of respect but made a conscious choice not to.
This choice is based on their insight into respect as a prerequisite for learning. It's easier to learn from someone you respect than from someone you don't. Respect opens the mind and loosens preconceived opinions to make room for new knowledge and skills. At the same time, people who value their knowledge feel more inclined to teach it to someone who shows respect than to someone who doesn't.
...
So when Buddhist parents teach their children to show respect for the Buddha, Dhamma, and Sangha, they aren't teaching them a habit that will later have to be unlearned. Of course, the child will need to discover how best to understand and make use of that respect, but at least the parents have helped open the door for the child to learn from its own powers of observation, to learn from the truth, and to learn from the insights of others. And when that door — when the mind — is opened to what truly deserves respect, all things noble and good can come in.
