चेतसा सर्वकर्माणि मयि सन्न्यस्य मत्परः । बुद्धियोगम् उपाश्रित्य मच्चितस् सदा भव ॥

cetasā sarva-karmāṇi mayi sannyasya mat-paraḥ | buddhi-yogam upāśritya mac-citas sadā bhava ||

Mentally offering all actions to Me, with Me as highest — resorting to buddhi-yoga, always be mind-in-Me.

Word by word (3)
cetasā sarva-karmāṇi mayi sannyasya mat-paraḥ
— mentally/with the mind/consciousness (cetasā = with-mind/consciousness) all actions (sarva-karmāṇi) having renounced/dedicated (sannyasya = having-surrendered, from san + nyāsa = complete-placing; sannyāsa used here as the action of offering-unto-Me) to Me (mayi), with Me as the highest/supreme (mat-paraḥ = mat + para = Me-as-highest)
buddhi-yogam upāśritya mac-citas sadā bhava
— having resorted to buddhi-yoga (the yoga of discriminating intelligence; buddhi-yoga = yoga that operates through the purified buddhi), always (sadā) be one whose mind is in Me (mac-citas = mac + citas = My-minded, mind-fixed-in-Me), be (bhava) — the practice instruction: buddhi-yoga + mac-citta = constant mental abidance in Me
cetasā sannyasya...mac-citas sadā bhava
— mentally renounce → keep mind constantly in Me; the two-movement practice: (1) cetasā sannyasya sarva-karmāṇi mayi = offer all actions mentally to Me (the sannyāsa that is internal, not external); (2) mac-citas sadā bhava = be perpetually mind-in-Me; this is the Gita's constant bhakti-yoga practice instruction for the person still engaged in worldly action (sarva-karmāṇi)

Mentally renouncing all actions to Me, with Me as the highest goal, resorting to buddhi-yoga — always be one whose mind is in Me.

A modern analogy

V57 gives the practice method for V56's 'refuge in Me.' The instruction: (1) mentally offer all actions to Krishna as you do them (cetasā sannyasya), (2) keep the Divine as the highest value/orientation (mat-paraḥ), (3) use the buddhi (discriminating intelligence) as the vehicle for this orientation (buddhi-yoga), and (4) maintain this mind-in-Me (mac-citas) always. This is not complicated technique but a continuous inner orientation.

V57 gives the method for V56's mad-vyapāśraya (refuge in Me): cetasā sarva-karmāṇi mayi sannyasya (mentally offering all actions to Me) + buddhi-yoga + mac-citas sadā. The word sannyasya here is significant: Krishna uses sannyāsa-language (normally associated with renunciation of action) for the INNER mental offering of all actions. This resolves the opening question of Ch.18 (sannyāsa vs. tyāga): the true sannyāsa is internal — offering all actions mentally to the Divine, not externally abandoning them.

Buddhi-yoga upāśritya (resorting to buddhi-yoga) connects V57 to Ch.2 V49's buddhau śaraṇam anviccha (seek refuge in buddhi). The buddhi-yoga is the inner alignment of the intelligence with the Divine — keeping the discriminating faculty (buddhi) oriented toward the Divine reality rather than toward sensory pleasures or ego-goals. Mac-citas sadā bhava (always be mind-in-Me) is the fruit of this buddhi-yoga: when the buddhi is consistently oriented toward the Divine, the citta (mind-substance) naturally follows.
