sukhāyu / sukhāyuḥ: what the term means and how it is translated
sukhāyu / sukhāyuḥ सुखायुः is an Ayurvedic technical term. It is rendered into English in 3 different ways, which is the reason this page exists: the renderings do not agree, and the difference between them changes what the term is taken to mean.

How it is translated, and whether the translation holds
Each rendering is given with the source that uses it. The assessment is ours.
High quality of life
WHO international standard terminologies on Ayurveda (WHO, 2022) · Term ID ITA-1.2.4, printed p. 2 · standard
WHO's description: 'A lifestyle characterized by a high quotient of happiness.' Recorded as a fact about WHO. Notable that WHO chose the modern health-services term 'quality of life', which imports an entire measurement literature (WHOQOL) that the classical definition does not support.

happy
Charaka Samhita, tr. Avinash Chandra Kaviratna (1896-1913) · Sutrasthana Lesson XXX, aphorism 19: 'Life is called happy' · translation
Public domain. Kaviratna's English term is 'happy Life'. He uses the same word at Su 1.41 ('Good, evil, happy and unhappy is Life'), so unlike hitāyu his rendering of this term is internally consistent.
blissful life
common Indian journal and textbook usage · textbook · our paraphrase of the source, not its words
Widespread in Indian Ayurvedic writing, often paired with 'useful life' for hitāyu. Stronger than sukha warrants; sukha in this verse is defined by the absence of disease and the presence of youth, strength, wealth and freedom of action, not by an inner state of bliss.
The classical passages
Each citation gives its address so a reader can check it in a printed edition, our account of what the passage establishes, and the result of reading it against its source.
Charaka SamhitaSutrasthana 30 (Arthedaśamahāmūlīya Adhyāya):24 · checked against the source
तत्र शारीरमानसाभ्यां रोगाभ्यामनभिद्रुतस्य विशेषेण यौवनवतः समर्थानुगतबलवीर्ययशःपौरुषपराक्रमस्यज्ञानविज्ञानेन्द्रियेन्द्रियार्थबलसमुदये वर्तमानस्य परमर्द्धिरुचिरविविधोपभोगस्य समृद्धसर्वारम्भस्य यथेष्टविचारिणःसुखमायुरुच्यते; असुखमतो विपर्ययेण
Defines sukham āyuḥ by: freedom from bodily and mental disease, youth in particular, strength/vigour/fame/manliness/prowess proportionate to capacity, command of knowledge, science, senses and sense-objects, great affluence and varied enjoyments, success in all undertakings, and moving as one wishes. Then defines its opposite as asukham, by reverse. This is an excerpt of the first portion of verse 24; the hitāyu portion follows in the same verse.
Charaka SamhitaSutrasthana Lesson XXX (Arthedaśamahāmūlīya):19 in Kaviratna's numbering · checked against the source
who is not afflicted by any disease physical or mental, who is, particularly, possessed of youth, who is endued with strength, energy, manliness, and prowess, proportioned to the capacity of his frame, who rests on strength of knowledge, of science, and of the senses, as also on all the objects of the senses, who is endued with great affluence and diverse agreeable objects of enjoyment, who is crowned with success in respect of all his essays, and who moves and acts as he pleases, Life is called happy.
The lawfully quotable English of the sukhāyu definition, matching the Sanskrit above clause for clause and in the same order. Note how much of it is circumstantial - wealth, success, freedom of action - which is what makes WHO's 'quotient of happiness' gloss a narrowing.
Charaka SamhitaSutrasthana 1 (Dīrghañjīvitīya Adhyāya):41 · checked against the source
हिताहितं सुखं दुःखमायुस्तस्य हिताहितम्| मानं च तच्च यत्रोक्तमायुर्वेदः स उच्यते||४१||
The first occurrence of sukha as a division of āyu, here as a bare adjective with no content.
Not to be confused with
- hitāyu
- Sukhāyu is about condition and circumstance (health, youth, wealth, success, freedom); hitāyu is about conduct (truthfulness, restraint, giving, reverence). They are independent axes, and the fourfold scheme exists precisely so that a life can be classified on both.
- sukha (as the counterpart of duḥkha in doṣa/health contexts)
- Sukha is used throughout the Samhitas for pleasant sensation and for the comfortable state of the body. In sukhāyu it qualifies a whole life, assessed by a checklist, not a sensation.
- svastha
- Freedom from disease is only the first item in the sukhāyu list; svastha is the technical term for that item alone. Sukhāyu is broader and includes wealth and success, which svastha does not.
- ānanda / moksha
- Sukhāyu is worldly and enumerable. Rendering it as bliss slides it toward a soteriological category the verse does not invoke.
Renderings that do not hold
- quality of life. WHO uses it, so it must be recorded, but it is an import: it carries the apparatus of QoL instruments and a self-report methodology alien to a verse that lists objective circumstances such as affluence and success in undertakings. Recording it as WHO's rendering is correct; adopting it as the definition is not.
- healthy life. Freedom from disease is one of nine or so items in the list.
- pleasant life. Understates. The list includes strength, prowess, fame and command of the senses, not merely pleasantness.
Open questions
Recorded rather than resolved. Each one is something this entry cannot currently settle.
- Why Su 30.24 uses asukham rather than duḥkham for the negative limb, when Su 1.41 uses duḥkham. This is a real lexical inconsistency in the source and I could not establish whether any commentator addresses it.
- Whether NAMASTE codes sukhāyu and whether it followed WHO into 'quality of life'.
