Not all emotions need to be controlled. Only bad emotions, worldly considerations and shallow desires need to be controlled. Good emotions are love, suffering, forbearance, patience, selfless service, etc. They don't need to be controlled. Mirabai taught us that our emotions should be focused towards God. Even bad emotions can be directed towards God if you can connect with Him.

In any case, most emotions in this world are harmful and must be controlled, through yama (truthfulness, love or nonviolence, continence, non­stealing or non-cheating, simplicity and morality) and niyama (purity of body and mind, satisfaction, self-study and surrender to God). Yama and niyama are the strong foundations to withstand any storm.
