Usually Bhakti is referred to unconditional love towards God, Worshiping God, Chanting his name and thinking of him day and night. And a bhakta who is completely Devoted to God in mind, body and soul will be liberated.
My question is, can someone have that intensity of bhakti towards his/her mother, father, husband, wife or any person other than God and get moksha?
bakthi
andbakthi yoga
are same, where the former is what you are referring to while the latter is the one that leads to liberation.
