Krushn said:  Born of the activating attribute of Nature (rajo-guna), it is desire, it is anger, (that is the impelling force)—full of unappeasable craving and great evil: know this (two-sided passion) to be the foulest enemy here on earth. Gita 3.37
As fire is enveloped by smoke, as a mirror by dust, as an embryo by the womb, so this (wisdom) is enveloped by that (desire). Gita 3.38

O Son of Kunti (Arjuna)! the constant enemy of wise men is the unslakable flame of desire, by which wisdom is concealed. Gita 3.39

The senses, mind, and intellect are said to be desire’s formidable stronghold; through these, desire deludes the embodied soul by eclipsing its wisdom. Therefore, O Best of the Bharata Dynasty (Arjuna)! first discipline the senses, then destroy desire, the sinful annihilator of wisdom and Self-realization.

Gita 3.40-41

Three types of desires described in Gita

Peaceful (satvic) – desire dominated by satva guna is like fire being choked with smoke. A slight breeze is enough to remove the smoke and bring out the flame in all its glory.
Restless (rajasic) – desire gushes out from a restless and selfish urge to acquire, possess and enjoy the sense-objects. This desire demands strenuous attempts for its removal.
Low (tamasic) – To remove the foetus in the womb, not only is effort required, but efflux of time as well. Time and self-preparations are necessary to eliminate the deep-rooted tamasic desire.

For sanctification of the ego, yogis perform actions solely with (the instruments of action) the body, the mind, discrimination, or even the senses, forsaking attachment (disallowing ego involvement, with its attachments and desires). Gita 5.11

They who, having taken refuge in Me, strive for deliverance from old age and death know Brahma(The absolute), the whole embodied souls, and the entire field of Karma(action) as well as My Integral being, comprising the field of matter, Brahma and the unmanifest Divinity dwelling in the heart of all beings as their witness. And they who, possessed of a steadfast mind, know thus even at the hour of death, they too know Me alone.

But those men of virtuous deeds, whose sins have come to an end, being freed from delusion in the shape of pairs of opposites born of attraction and repulsion, worship Me with a firm resolve in every way.

[Shlok 27, Adhyay 7]

O valiant Arjuna, through delusion in the shape of pairs of opposites (such as pleasure and pain) born of desire and aversion, all living creatures in this world are falling a prey to infatuation.
