A little more than 100 years ago, the science of physics discovered that all material objects did not actually exist by themselves, but consisted of atoms. Over the following decades, physicists gradually learned that atoms did not exist by themselves either, but consisted of rapidly fluctuating subatomic entities that emerged from the unknown, only to almost instantly disappear again. These discoveries were made by colliding atoms and various composite subatomic entities with each other and analyzing the traces left behind. The traces proved that the colliding particles indeed were composites of even tinier entities, which were named quarks, leptons and bosons. The laboratory experiments went hand in hand with extensive mathematical calculations that formed the basis of quantum field theory, according to which there is no such thing as stable elementary particles – rather, it is a question of small vibrating packets of not understood basic energy forms.
More than 2000 years earlier, Buddhist monks and scholars discovered and analyzed similar phenomena and came to very similar conclusions. While physicists focus on the material aspects of reality, neglecting the existence of mind and consciousness, Buddhist monks and scholars explored similar phenomena with a primary emphasis on the mental and spiritual realms. Their discoveries and conclusions were formulated in the Abhidhamma – a prominent part of the canonical Buddhist literature – of which the Patthana is the seventh and final book.
The Theravada counterpart to the term ‘elementary particle’ is the term ‘dhamma’. All things are ultimately nothing but manifestations of dhammas. There are four dhamma types named citta, cetasika, rupa, and nibbana. While not identical by any stretch or in any way, the dhamma types can be considered Patthana counterparts to quarks, leptons, and bosons. Citta, cetasika and rupa dhammas are conditioned by other things. Nibbana on the other hand is not conditioned by anything.
Citta is consciousness. It is the nature which is capable of knowing, sensing or being aware of objects. Examples of citta include the visual consciousness, auditory consciousness, olfactory consciousness, gustatory consciousness, tactile consciousness, and cognitive consciousness. Cetasika always arises with citta and disappears with citta. Examples of cetasikas are irritation, anger, hatred, rage, jealousy, craving, ignorance, depression, fearlessness, shamelessness, love, attachment, clinging, conceit and many more. Rupa is material, all matter — solids, liquids, gases, molecules, atoms, quarks, leptons, etc. is made up of rupa dhammas. Nibbana is the ultimate reality — i.e the supreme, fundamental, and objective truth underlying all existence, transcending any sensory perception.
According to Patthana, there are (usually) 89 different citta dhammas, 52 cetasika dhammas, 28 rupa dhammas and 1 nibbana dhamma. In certain advanced meditative states, 32 more citta dhammas may appear. In this section, all of these dhammas and their interactions will be described in more detail.
