It is the most natural path for seeking emotional fulfillment, it leads to the realization of the Divine and well-being by means of devotion, faith and love. Bhakti is a Yoga of devotion or complete faith. This faith is generally in the God or supreme consciousness in any of the forms. It may be Lord Rama, Krishna, Christ, Mohammed, Buddha etc. It may be a Guru for his disciples.
An important thing is that a person interested in following this path should have very strong emotional bond with the object of faith. The flow of emotional energy is directed to this object. Most of the people suppress their emotions and that often reflects in the form of physical and mental disorders. This Bhakti Yoga releases those suppressed emotions and brings purification to the inner self.
Continuous meditation on God or on the object of faith gradually decreases the ego of the practitioner, which further prevents new distractions, fickleness or even pain and induces strong bonds of love. Slowly the practitioner looses the self identity and becomes one with the object of faith, this is a state of self realization. When someone surrenders his-self completely with gratitude to the Supreme or God without any doubt then the person doesn’t face any single pain in his life. When Bhakti and Love combined together it becomes Shradha (purest form of devotion).
