Theravada recognizes four jhanas based on early Buddhist texts; other schools added formless states or subdivided existing ones differently.
Theravada Buddhism, based primarily on the Pali Canon, describes four jhanas (meditative absorptions) as progressively deeper states of mental concentration. The first jhana involves applied attention, sustained attention, joy, happiness, and one-pointedness of mind while withdrawing from sensory objects. The second jhana deepens this by removing applied and sustained attention, leaving unified attention with joy and happiness. The third jhana replaces joy with equanimity and subtle happiness. The fourth jhana reaches a state of pure equanimity and neutral feeling, with perfect mental clarity.
These four states appear consistently across Pali texts including the Digha Nikaya, Majjhima Nikaya, and the Visuddhimagga (Path of Purification), Theravada's authoritative meditation manual composed by Buddhaghosa around the 5th century. The structure reflects a methodical progression inward, where each stage eliminates coarser mental factors to reveal subtler ones.
Some Buddhist schools and texts reference five, six, or even eight meditative states by including the formless absorptions (arupajhanas) alongside the four material-realm jhanas. These formless states—the sphere of infinite space, infinite consciousness, nothingness, and neither-perception-nor-non-perception—appear in the Pali Canon itself, particularly in the Samyutta Nikaya. However, Theravada traditionally categorizes these as distinct from the four jhanas proper, treating them as a separate sequence that arises after mastering the fourth jhana.
Mahayana and other schools sometimes integrate these more fluidly into a single ascending ladder of meditation, presenting them numerically as the fifth, sixth, seventh, and eighth attainments. This difference reflects not a disagreement about what these states are, but rather a classification choice: whether to keep them in separate categories or present them as a unified continuum.
The canonical basis for the four-jhana model is explicit and early. The Buddha describes the four jhanas repeatedly in foundational texts like the Brahmajalasutta (Digha Nikaya 1) and the Samadhi-sutta (Majjhima Nikaya 78). These accounts consistently describe the same four stages without subdividing them further. The Abhidhamma, Theravada's scholastic philosophical texts, also upholds this four-fold structure as the standard framework for understanding concentration within the material realm.
When the Pali texts discuss what Western interpreters sometimes call "fifth" or "sixth" jhanas, they are explicitly named as formless attainments (arupajhana) and presented as a separate progression. This textual clarity is one reason Theravada maintains the four-jhana designation: it faithfully reflects how the early texts themselves delineate these experiences.
Some schools subdivide the four jhanas further based on nuanced differences in the arising of mental factors. For instance, certain Mahayana and tantric traditions distinguish between preliminary jhana stages and "full" jhanas, effectively creating eight or nine distinct experiences from the same basic progression. These subdivisions are sometimes grounded in detailed phenomenological analysis rather than fundamental disagreement about what occurs at each level.
Theravada's four-jhana model represents a middle path: comprehensive enough to account for the major qualitative shifts in consciousness, yet not so subdivided as to fragment what Buddhist texts present as unified stages. The Visuddhimagga provides extremely detailed analysis of each jhana's mental factors, but maintains the four-stage framework throughout.
The four-jhana model in Theravada reflects both textual fidelity and practical contemplative wisdom. The progression represents genuine transformations in consciousness: sensory withdrawal and joy (first), refined mental unification (second), replacement of joy with stable happiness (third), and transcendence into pure equanimity (fourth). These mark meaningful thresholds, not arbitrary divisions.
Theravada's decision to keep formless states separate acknowledges that after the fourth jhana, consciousness enters a fundamentally different realm—no longer tied to the body's sensory basis. This structural distinction proves useful for practitioners, teachers, and scholars seeking clarity about where profound transitions occur in meditation. While other traditions organize these same experiences differently, the Theravada four-jhana framework remains internally coherent, well-documented, and practically sound.
