Bg 3.7

yas tv indriyani manasa
niyamyarabhate ’rjuna
karmendriyaih karma-yogam
asaktah sa visisyate

Word for word: 
yah — one who; tu — but; indriyani — the senses; manasa — by the mind; niyamya — regulating; arabhate — begins; arjuna — O Arjuna; karma-indriyaih — by the active sense organs; karma-yogam — devotion; asaktah — without attachment; sah — he; visisyate — is by far the better.

Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
On the other hand, if a sincere person tries to control the active senses by the mind and begins karma-yoga [in Krishna consciousness] without attachment, he is by far superior.

Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Instead of becoming a pseudo transcendentalist for the sake of wanton living and sense enjoyment, it is far better to remain in one’s own business and execute the purpose of life, which is to get free from material bondage and enter into the kingdom of God. The prime svartha-gati, or goal of self-interest, is to reach Visnu. The whole institution of varna and asrama is designed to help us reach this goal of life. A householder can also reach this destination by regulated service in Krishna consciousness. For self-realization, one can live a controlled life, as prescribed in the sastras, and continue carrying out his business without attachment, and in that way make progress. A sincere person who follows this method is far better situated than the false pretender who adopts show-bottle spiritualism to cheat the innocent public. A sincere sweeper in the street is far better than the charlatan meditator who meditates only for the sake of making a living.
