Srila Prabhupada's Purport BG 3.37

The Supreme Personality of Godhead expanded Himself into many for His ever-increasing spiritual bliss, and the living entities are parts and parcels of this spiritual bliss. They also have partial independence, but by misuse of their independence, when the service attitude is transformed into the propensity for sense enjoyment, they come under the sway of lust. This material creation is created by the Lord to give facility to the conditioned souls to fulfill these lustful propensities, and when completely baffled by prolonged lustful activities, the living entities begin to inquire about their real position.

This inquiry is the beginning of the Vedānta-sūtras, wherein it is said, athāto brahma-jijñāsā: one should inquire into the Supreme. And the Supreme is defined inŚrīmad-Bhāgavatam as janmādy asya yato ’nvayād itarataś ca, or, “The origin of everything is the Supreme Brahman.” Therefore the origin of lust is also in the Supreme. If, therefore, lust is transformed into love for the Supreme, or transformed into Kṛṣṇa consciousness – or, in other words, desiring everything for Kṛṣṇa – then both lust and wrath can be spiritualized. Hanumān, the great servitor of Lord Rāma, exhibited his wrath by burning the golden city of Rāvaṇa, but by doing so he became the greatest devotee of the Lord. Here also, in Bhagavad-gītā, the Lord induces Arjuna to engage his wrath upon his enemies for the satisfaction of the Lord. Therefore, lust and wrath, when they are employed in Kṛṣṇa consciousness, become our friends instead of our enemies.
