Dosha & Constitution
Sattva, Rajas And Tamas As A Mental Constitution
Alongside the three doshas, Ayurveda uses three mental qualities to describe temperament, a scheme drawn from philosophy rather than physiology and evaluative by design.

Alongside the physical constitution, the classical texts describe a mental one built from three qualities: sattva, rajas and tamas. It comes from a different intellectual source and behaves differently.
Where the three qualities come from
The gunas are a concept from Samkhya philosophy, describing the composition of the material world generally, and Ayurveda inherits them rather than deriving them medically.
Sattva is associated with clarity, steadiness and balance, rajas with movement, activity and agitation, and tamas with inertia, heaviness and dullness.
Unlike the doshas, these three are explicitly evaluative, with sattva presented as desirable and the other two as states to be moderated.
How they describe temperament
A predominantly sattvic temperament is described as calm, attentive and even, a rajasic one as driven, restless and quick to react, and a tamasic one as slow, avoidant and heavy.
The texts subdivide these into many finer types, giving character portraits that read as personality description rather than as clinical categories.
The scheme is used to advise on conduct, occupation, company and study, so its application is behavioural rather than pharmacological.
The moral dimension is explicit
Because the qualities are ranked, describing someone as tamasic carries a judgement in a way that describing them as kapha does not.
This matters, because applying the framework to fatigue, low mood or withdrawal risks recasting symptoms of illness as moral failings.
Depression, chronic fatigue and hypothyroidism can all present as heaviness and reduced motivation, and none of them is a character quality.
What is being described in modern terms
Some of the descriptions overlap loosely with personality dimensions studied in psychology, particularly around arousal, impulsivity and emotional stability.
Attempts have been made to build questionnaires around these categories and to relate them to established personality inventories, with results that are preliminary at best.
No mapping onto psychiatric diagnosis exists or should be attempted, since the categories were built for a different purpose in a different framework.
The practices attached to the scheme
The recommendations aimed at increasing sattva concern diet, sleep regularity, company, study and meditative practice, and most are unobjectionable as lifestyle advice.
Where they become concerning is when withdrawal from ordinary life is presented as spiritual progress, or when medication is framed as tamasic.
Anyone experiencing persistent low mood, anxiety or loss of function needs mental health care, and no traditional classification of temperament changes that.
