B.G 4.33
śreyān dravyamayād yajñājjñānayajñaḥ parantapa। sarvaṁ karmākhilaṁ pārtha jñāne parisamāpyate ॥33॥
O Parantapa, sacrifice of knowledge, is more beneficial than the sacrifices of wealth. O Partha, all deed culminates in the attainment of wholesome wisdom.

All deeds by nature are limited, they become 'akhilam', i.e. wholesome, when they become complete by the birth of wisdom. 'samāpyate' - is used to mean 'culmination' and not 'end'. Inaction is not recommended here, as the chapter ends, asking Arjuna to fight having situated himself in Yōga.

All deeds by nature are limited, they become 'akhilam', i.e. wholesome, when 'jñāne parisamāpyate' i.e. they become complete by the birth of wisdom.
