B.G 3.09
यज्ञार्थात् कर्मणोन्यत्र लोकोयं कर्मबन्धनः। तदर्थं कर्म कौन्तेय मुक्तसङ्गः समाचर ॥९॥
Actions must be performed as a sacrifice to worship the Lord. Otherwise, actions performed for the wordly sake lead to bondage. So, practice actions without attachment, with equanimity, for His sake.
Gīta Tātparya 3.09
'Jna' means lord Vishnu. 'Yajna' means prescribed duties to be performed for lord Vishnu's sake.
"कर्मणा बध्यते जन्तुः"
"Beings are bound by action."
इत्यादिकमपि अवैष्णवकर्मविषयमित्याह - यज्ञार्थादिति।
Such statements are meant for non Vaishnava actions. Hence in the 'Yajna' verse it is told, perform action for the sake of 'Yajna'.
"ज्ञो नाम भगवान् विष्णुः तं यात्युद्देश एष यः। स यज्ञ इति सम्प्रोक्तो विहिते कर्मणि स्थितः॥"
इति बर्कश्रुतिः ॥९॥
"Lord Vishnu is known by the name 'Jna' (the knowledgeable). The stated prescribed duties to be performed for His sake are said to be 'Yajna'."
