In the oldest texts of Buddhism, dhyāna (ध्यान) or jhāna (𑀛𑀸𑀦) is a component of the training of the mind (bhavana), commonly translated as meditation, to withdraw the mind from the automatic responses to sense-impressions, "burn up" the defilements, and leading to a "state of perfect equanimity and awareness (upekkhā-sati-parisuddhi)." Dhyāna may have been the core practice of pre-sectarian Buddhism, in combination with several related practices which together lead to perfected mindfulness and detachment.
In the later commentarial tradition, which has survived in present-day Theravāda, dhyāna is equated with "concentration", a state of one-pointed absorption in which there is a diminished awareness of the surroundings. In the contemporary Theravāda-based Vipassana movement, this absorbed state of mind is regarded as unnecessary and even non-beneficial for the first stage of awakening, which has to be reached by mindfulness of the body and Vipassanā (insight into impermanence). Since the 1980s, scholars and practitioners have started to question these positions, arguing for a more comprehensive and integrated understanding and approach, based on the oldest descriptions of dhyāna in the suttas.
In Buddhist traditions of Chán and Zen (the names of which are, respectively, the Chinese and Japanese pronunciations of dhyāna), as in Theravada and Tiantai, anapanasati (mindfulness of breathing), which is transmitted in the Buddhist tradition as a means to develop dhyana, is a central practice. In the Chan/Zen-tradition this practice is ultimately based on Sarvastivāda meditation techniques transmitted since the beginning of the Common Era.
Dhyāna, Pali jhana, from Proto-Indo-European root *√dheie-, "to see, to look", "to show". Developed into Sanskrit root √dhī and n. dhī, which in the earliest layer of text of the Vedas refers to "imaginative vision" and associated with goddess Saraswati with powers of knowledge, wisdom and poetic eloquence. This term developed into the variant √dhyā, "to contemplate, meditate, think", from which dhyāna is derived.
