Just as the destination of a glowing fire Struck with a [blacksmith’s] iron hammer, Gradually growing calm, Isn’t known: Even so, there’s no destination to describe For those rightly released Having crossed over the flood of sensuality’s bond For those who’ve attained Unwavering bliss. Ud 8.10 Dabba Sutta. Theravada Buddhism.
The Buddha considered the practice of Skillful Speech so essential to one's personal and spiritual development that he gave it its own step on the path to happiness. Skillful Speech, the Buddha told us, has four qualities: It is always truthful. It is uplifting, not malicious or unkind. It is gentle, not crude or harsh. It is moderate, not useless or meaningless.
