From last 5 years I am not able to decide my spiritual master because I want to have proper dedication and love towards my spiritual master so that I can follow all his instructions in all circumstances. And to develop love and appreciation for some person we need to see his contribution in our life or spend some time living with the person but because of organization being so large we don't get personal association of sannyasis. He is our deliverer is true but I am not able to realize that in my current situation and this also doesn't helps me a lot. I have asked many devotees and they have answered that they saw their spiritual and they get the internal call that he is your guru and some develop love just from one interaction with with their spiritual master and accepted him as their spiritual master. Most commonly devotees accept the spiritual master of their siksha guru as their spiritual master or sometimes some one likes somebody's kirtan or lecture or anything and on that basis they accept.
My question is that what is the criteria for selecting a spiritual master and how we can develop love and dedication towards him as a person without spending time with him personally.
