अनुद्वेगकरं वाक्यं सत्यं प्रियहितं च यत् । स्वाध्यायाभ्यसनं चैव वाङ्मयं तप उच्यते ॥

anudvega-karaṃ vākyaṃ satyaṃ priya-hitaṃ ca yat | svādhyāyābhyasanaṃ caiva vāṅ-mayaṃ tapa ucyate ||

Speech tapas: non-disturbing, true, agreeable, beneficial words — plus daily svādhyāya (sacred study).

Word by word (3)
anudvega-karaṃ vākyaṃ satyaṃ priya-hitaṃ ca yat
— speech/words (vākyam) that do not cause excitement/distress (anudvega-karam = not-agitation-making), that are true (satyam), agreeable (priya) and beneficial (hitam) — the four-fold standard of sattvic speech
svādhyāyābhyasanam ca eva
— and also (ca eva) the regular practice (abhyasana) of svādhyāya — the study/recitation of one's own sacred texts (sva = own, adhyāya = study/lesson); daily sacred recitation as speech-tapas
vāṅ-mayaṃ tapa ucyate
— this is called (ucyate) the tapas of speech/words (vāṅ-maya = consisting of speech/vāk) — vāk (speech) as a domain of tapas parallel to śārīra (body) from V14

Speech that causes no distress, that is true, agreeable, and beneficial — and also the regular practice of sacred recitation (svādhyāya) — these are called the austerity of speech.

A modern analogy

Speech tapas means treating every word as a small offering. Before speaking, asking: Is this true? Will it disturb? Is it genuinely useful? Would it harm? And alongside this, the discipline of daily sacred recitation — keeping one's speech-instrument tuned to the sacred register through regular use in that direction.

V15 describes tapas of speech (vāṅ-maya tapas), the middle level between bodily (V14) and mental tapas (V16). The four-fold standard — anudvega-kara, satya, priya, hita — is the Gita's most compact speech ethics. Notably, the four are cumulative: speech that is true but causes needless distress is not sufficient; truth must also be agreeable in delivery and genuinely beneficial in purpose. Svādhyāya (sacred study) is included as a speech-tapas because recitation (pāṭha) is itself a use of speech in the highest register.

The sequence anudvega-kara → satya → priya → hita maps a hierarchy of speech qualities: the first (non-disturbing) is the minimum ethical standard; satya (truth) is the substantive content; priya (agreeable) concerns how truth is delivered; hitam (beneficial) concerns its effect. The Gita thus rejects both harsh truth-telling (satya but not priya) and pleasant falsehood (priya but not satya). Only speech that meets all four criteria qualifies as tapas. Svādhyāya adds a fifth dimension: even solitary sacred recitation is speech-discipline.
