Gunas

Guṇa, depending on the context means ‘string,
thread or strand’, or ‘virtue, merit, excellence’,
or ‘quality, peculiarity, attribute, property’.

There are three guṇas. They are called:
sattva (goodness, constructive, harmonious),
rajas (passion, active, confused), and
tamas (darkness, destructive, chaotic).

All of these three gunas are present in
everyone and everything, it is the proportion
that is different. The interplay of these gunas
defines the character of someone or something,
of nature and determines the progress of life.

In some contexts, it may mean ‘a subdivision,
species, kind, quality’, or an operational
principle or tendency of something or someone.
In human behavior, Guna means personality,
innate nature and psychological attributes
of an individual.
