The Blessed Lord said: O sinless Arjuna, I have already explained that there are two classes of men who realize the Self. Some are inclined to understand Him by empirical, philosophical speculation, and others are inclined to know Him by devotional work.
Work done as a sacrifice for Viṣṇu has to be performed, otherwise work binds one to this material world. Therefore, O son of Kuntī, perform your prescribed duties for His satisfaction, and in that way you will always remain unattached and free from bondage.
In the beginning of creation, the Lord of all creatures sent forth generations of men and demigods, along with sacrifices for Viṣṇu, and blessed them by saying, “Be thou happy by this yajña [sacrifice] because its performance will bestow upon you all desirable things.”
In charge of the various necessities of life, the demigods, being satisfied by the performance of yajña [sacrifice], supply all necessities to man. But he who enjoys these gifts, without offering them to the demigods in return, is certainly a thief.
Regulated activities are prescribed in the Vedas, and the Vedas are directly manifested from the Supreme Personality of Godhead. Consequently the all-pervading Transcendence is eternally situated in acts of sacrifice.
One who is in knowledge of the Absolute Truth, O mighty-armed, does not engage himself in the senses and sense gratification, knowing well the differences between work in devotion and work for fruitive results.
Bewildered by the modes of material nature, the ignorant fully engage themselves in material activities and become attached. But the wise should not unsettle them, although these duties are inferior due to the performers' lack of knowledge.
Attraction and repulsion for sense objects are felt by embodied beings, but one should not fall under the control of senses and sense objects because they are stumbling blocks on the path of self-realization.
It is far better to discharge one's prescribed duties, even though they may be faulty, than another's duties. Destruction in the course of performing one's own duty is better than engaging in another's duties, for to follow another's path is dangerous.
The Blessed Lord said: It is lust only, Arjuna, which is born of contact with the material modes of passion and later transformed into wrath, and which is the all-devouring, sinful enemy of this world.
Thus knowing oneself to be transcendental to material senses, mind and intelligence, one should control the lower self by the higher self and thus-by spiritual strength-conquer this insatiable enemy known as lust.
