Thai Forest Tradition's exposition, awareness of the deathless is boundless and unconditioned and cannot be conceptualized, and must be arrived at through mental training which includes states of meditative concentration (Pali: jhana). Forest teachers thus directly challenge the notion of "dry insight" (insight without any development of concentration), and teach that nibbāna must be arrived at through mental training which includes deep states of meditative concentration (Pali: jhāna), and "exertion and striving" to "cut" or "clear the path" through the "tangle" of defilements, setting awareness free, and thus allowing one to see them clearly for what they are, eventually leading one to be released from these defilements. Kammaṭṭhāna — The Place of Work Kammaṭṭhāna, (Pali: meaning “place of work”) refers to the whole of the practice with the goal of ultimately eradicating defilement from the mind. The practice which monks in the tradition generally begin with are meditations on what Ajahn Mun called the five "root meditation themes": the hair of the head, the hair of the body, the nails, the teeth, and the skin. One of the purposes of meditating on these externally visible aspects of the body is to counter the infatuation with the body, and to develop a sense of dispassion. Of the five, the skin is described as being especially significant. Ajahn Mun writes that "When we get infatuated with the human body, the skin is what we are infatuated with. When we conceive of the body as being beautiful and attractive, and develop love, desire, and longing for it, it's because of what we conceive of the skin." Advanced meditations include the classical themes of contemplation and mindfulness of breathing: The ten recollections: a list of ten meditation themes considered especially significant by the Buddha. The asubha contemplations: contemplations of foulness for combating sensual desire. The brahmaviharas: assertions of good-will for all beings to combat ill-will. The four satipatthana: frames of reference to get the mind into deep concentration Mindfulness immersed in the body and mindfulness of in-and-out breathing (ānāpānasati) are both part of the ten recollections and the four satipatthana, and are commonly given special attention as primary themes for a meditator to focus on.
