Though the above mentioned persons belong to hinduism we cant say them as followers of dharma shastras! They have their own principles which contradict with many places in dharma shastras! thats why we say their doctorine doesnt belong to SATH (good)SAMPRADAYA!Only good aspects in them that doesnt contradict with dharma shastras must be followed by brahmins!They should not be considered as ideals for brahmins! Ideals should be Adi shankara,ramanuja,madhwacharya ..... who was within varnaashrama dharma (sanyasa ashrama).so,they r called as NIYAMA VAIDHEEKA SANYASIS.
But the people above said r ANIYAMA AVAIDHEEKAS.For heaven sake dont follow their activities like going abroad etc which r against shastras if u r a brahmin!
