Daily Reading: Bhagvad Gita As it is- Page-123

Bg 3.25

saktāḥ karmaṇy avidvāṁso
yathā kurvanti bhārata
kuryād vidvāṁs tathāsaktaś
cikīrṣur loka-saṅgraham

Translation: 

As the ignorant perform their duties with attachment to results, the learned may similarly act, but without attachment, for the sake of leading people on the right path.

Purport: 

A person in Kṛṣṇa consciousness and a person not in Kṛṣṇa consciousness are differentiated by different desires. A Kṛṣṇa conscious person does not do anything which is not conducive to development of Kṛṣṇa consciousness. He may even act exactly like the ignorant person, who is too much attached to material activities, but one is engaged in such activities for the satisfaction of his sense gratification, whereas the other is engaged for the satisfaction of Kṛṣṇa. Therefore, the Kṛṣṇa conscious person is required to show the people how to act and how to engage the results of action for the purpose of Kṛṣṇa consciousness.

Bg 3.26

na buddhi-bhedaṁ janayed
ajñānāṁ karma-saṅginām
joṣayet sarva-karmāṇi
vidvān yuktaḥ samācaran

Translation: 

So as not to disrupt the minds of ignorant men attached to the fruitive results of prescribed duties, a learned person should not induce them to stop work. Rather, by working in the spirit of devotion, he should engage them in all sorts of activities [for the gradual development of Kṛṣṇa consciousness].

Purport: 

Vedaiś ca sarvair aham eva vedyaḥ. That is the end of all Vedic rituals. All rituals, all performances of sacrifices, and everything that is put into the Vedas, including all direction for material activities, are meant for understanding Kṛṣṇa, who is the ultimate goal of life. But because the conditioned souls do not know anything beyond sense gratification, they study the Vedas to that end. But through fruitive activities and sense gratification regulated by the Vedic rituals one is gradually elevated to Kṛṣṇa consciousness. Therefore a realized soul in Kṛṣṇa consciousness should not disturb others in their activities or understanding, but he should act by showing how the results of all work can be dedicated to the service of Kṛṣṇa. The learned Kṛṣṇa conscious person may act in such a way that the ignorant person working for sense gratification may learn how to act and how to behave. Although the ignorant man is not to be disturbed in his activities, a slightly developed Kṛṣṇa conscious person may directly be engaged in the service of the Lord without waiting for other Vedic formulas. For this fortunate man there is no need to follow the Vedic rituals, because by direct Kṛṣṇa consciousness one can have all the results one would otherwise derive from following one’s prescribed duties.
