B.G 5.07

योगयुक्तो विशुद्धात्मा विजितात्मा जितेंद्रियः। सर्वभूतात्मभूतात्मा कुर्वन्नपि न लिप्यते ॥७॥

Yōgayukto viśuddhātmā vijitātmā jiteṁdriyaḥ। sarvabhūtātmabhūtātmā kurvannapi na lipyate ॥7॥

[योगयुक्तो विशुद्धात्मा विजितात्मा जितेंद्रियः। सर्वभूत आत्म भूतात्मा कुर्वन्नपि न लिप्यते॥
Yōgayukto = engaged in Yoga; viśuddhātmā = pure being; vijitātmā = is also the specially victorious being; jiteṁdriyaḥ = who has conquered all the faculties; । sarvabhūta = all beings; ātma = the essence; bhūtātmā = essence of beings; kurvannapi= even while performing; na = not; lipyate = is affected by defects; ]

That pure being who is engaged in Yoga, is specially victorious having conquered all the faculties and has the understanding that 'the lord of all beings is also my lord'. Faults do not affect such a person, even if they engage in action.

Gīta Bhāshya 5.07

The Lord is the master of all beings. Such a lord is within me, and enables all the activities of mine. Such an understanding is 'sarvabhūtātma bhūtātmā'.

एतदेव प्रपञ्चयति - योगयुक्तः इति। सर्वभूतात्म भूतः परमेश्वरः। 'यच्चाप्नोति' इत्यादेः। स आत्मभूतः स्वसमीपं प्रति आदानादिकर्ता यस्य सः सर्वभूतात्म भूतात्मा ॥७॥

etadeva prapañcayati - Yōgayuktaḥ iti। sarvabhūtātma bhūtaḥ parameśvaraḥ। 'yaccāpnoti' ityādeḥ। sa ātmabhūtaḥ svasamīpaṁ prati ādānādikartā yasya saḥ sarvabhūtātma bhūtātmā ॥7॥

[एतदेव (etadeva) - This alone; प्रपञ्चयति (prapañcayati) - explains; योगयुक्तः (Yōgayuktaḥ) - one united with Yōga; इति (iti) - thus; सर्वभूतात्म (sarvabhūtātma) - the soul of all beings; भूतः (bhūtaḥ) - having become; परमेश्वरः (parameśvaraḥ) - the Supreme Lord; यच्च (yacca) - whatever; आप्नोति (āpnoti) - achieves; स (sa) - that; आत्मभूतः (ātmabhūtaḥ) - being the soul; स्वसमीपं (svasamīpaṁ) - near oneself; प्रति (prati) - towards; आदानादिकर्ता (ādānādikartā) - the giver of taking and other actions; यस्य (yasya) - whose; सः (saḥ) - that; सर्वभूतात्म (sarvabhūtātma) - the soul of all beings; भूतात्मा (bhūtātmā) - the soul of all beings;]

The verse 'Yōgayuktaḥ', i.e. one engaged in Yōga, explains the state of the person engaged in Yōga. The Supreme Lord, Parameshwara, is the becoming and essence of all beings. It is explained by verses such as 'yaccāpnoti' (Linga puranam 1.70.96), i.e. 'whatever one achieves'. He is the essence of beings; He is the one who is near oneself; one who enables all the activities of the beings. Such an understanding is "sarvabhūtātma bhūtātmā", i.e. "the essence of all beings and that of individual being as well".

Note:

"यच्चाप्नोति यदादत्ते यच्चात्ति विषयानिह । यच्चास्य सन्ततो भावयस्तस्मादात्मेति कीर्त्यते॥" - Linga puranam 1.70.96
"Whatever one achieves, receives, and eats, as well as whatever objects one regularly thinks of, of Him, therefore, the Ātman is celebrated as such."
