Mahābhūta

Fundamental elements in Indian philosophy

Mahābhūta is Sanskrit and Pali for "great element". However, very few scholars define the five mahābhūtas in a broader sense as the five fundamental aspects of physical reality.

In Buddhism, the four Great Elements (Pali: cattāro mahābhūtāni) are earth, water, fire and air. Mahābhūta is generally synonymous with catudhātu, which is Pāli for the "Four Elements." In this, the Four Elements are a basis for understanding that leads one through unbinding of 'Rupa' or materiality to the supreme state of pure 'Emptiness' or Nirvana.

In the Pali Canon, the most basic elements are usually identified as four in number but, on occasion, a fifth and, to an even lesser extent, a sixth element may also be identified.

In canonical texts, the four Great Elements refer to elements that are both "external" (that is, outside the body, such as a river) and "internal" (that is, of the body, such as blood). These elements are described as follows:

Earth element (pruṭhavī dhātu)Earth element represents the quality of solidity or attractive forces. Any matter where attractive forces are in prominence (solid bodies) are called earth elements. Internal earth elements include head hair, body hair, nails, teeth, skin, flesh, sinews, bone, organs, intestinal material, etc. Water element (āpa dhātu)Water element represents the quality of liquidity or relative motion. Any matter where relative motion of particles is in prominence are called water elements. Internal water elements include bile, phlegm, pus, blood, sweat, fat, tears, nasal mucus, urine, semen, etc. Fire element (teja dhātu)Fire element represents the quality of heat or energy. Any matter where energy is in prominence are called fire elements. Internal fire elements include those bodily mechanisms that produce physical warmth, ageing, digestion, etc. Air (or wind) element (vāyu dhātu)Air element represents the quality of expansion or repulsive forces. Any matter where repulsive forces are in prominence are called air elements. Internal air elements includes air associated with the pulmonary system (for example, for breathing), the intestinal system ("winds in the belly and bowels"), etc. Any entity that carry one or more of these qualities (attractive forces, repulsive forces, energy and relative motion) are called matter (rupa). The material world is considered to be nothing but a combination of these qualities arranged in space (akasha). The result of these qualities are the inputs to our five senses, color (varna) to the eyes, smell (gandha) to the nose, taste (rasa) to the tongue, sound (shabda) to the ears, and touch (sparsha) to the body. The matter that we perceive in our mind are just a mental interpretation of these qualities.

While in the Theravada tradition, as well as in the earliest texts, like the Pali Canon, rūpa (matter or form) is delineated as something external, that actually exists, in some of the later schools, like the Yogachara, or "Mind Only" school, and schools heavily influenced by this school, rupa means both materiality and sensibility—it signifies, for example, a tactile object both insofar as that object is tactile and that it can be sensed. In some of these schools, rūpa is not a materiality which can be separated or isolated from cognizance; such a non empirical category is incongruous in the context of some schools of Mahayana and Vajrayana Buddhism. In the Yogacara view, rūpa is not a substratum or substance which has sensibility as a property. For this school, it functions as perceivable physicality and matter, or rūpa, is defined in its function; what it does, not what it is. As such, the four great elements are conceptual abstractions drawn from the sensorium. They are sensorial typologies, and are not metaphysically materialistic. From this perspective, they are not meant to give an account of matter as constitutive of external, mind independent reality. This interpretation was hotly contested by some Madhyamaka thinkers like Chandrakirti.

The Four Elements are used in Buddhist texts to both elucidate the concept of suffering (dukkha) and as an object of meditation. The earliest Buddhist texts explain that the four primary material elements are the sensory qualities solidity, fluidity, temperature, and mobility; their characterisation as earth, water, fire, and air, respectively, is declared an abstraction – instead of concentrating on the fact of material existence, one observes how a physical thing is sensed, felt, perceived.
