There are three sorts of Dhamma: the Dhamma of theory, the Dhamma of practice, and the Dhamma of attainment.

The Dhamma of theory refers to the teachings of the Buddha: the discourses, the discipline, the Abhidhamma, all 84,000 sections of the Pali canon. This sort of Dhamma is everyone's common property.

As for practice and attainment, they're the individual property of those who do them. For example, Ven. Moggallana's practice was his own practice. His attainment of the paths and fruitions leading to nibbana was his own attainment. The same holds true for Ven. Sariputta and each of the noble disciples, all the way down to all of us practicing here. The practice and attainments of each person are that person's very own. It's like your own land and fields. They belong to you; they're not common property. (Ajahn Khamdee)
