Devotee: Śrīla Prabhupāda, originally the desires come from the subtle body or from the soul?
Prabhupāda: No, mind.
Devotee: The mind.
Prabhupāda: Soul is now dependent on the mind; therefore mind has to be trained up. That is called yoga. Those who are too much in the bodily concept of life, the haṭha-yoga is recommended to control the mind. Yoga-indriya-saṁyamaḥ: "Yoga means to control the senses." So senses... The mind is the master of the senses. Therefore controlling the mind, yoga-indriya-saṁyamaḥ.
