Sridhara Swami's Commentary
Having pointed out the defect of not having the external physical senses under control, the defect in not having the mind under control is now being given in these two verses. For one who is given to dreaming about sensual pursuits considering them worthy of indulgence a strong attachment develops for them. From this strong attachment arises addicting desires for them, from these addicting desires flares up anger when these addicting desires are not satisfied.
