True while Ramana Maharishi was in physical form

Not all places are able to maintain the pure vibrations that were present when the saint was there. Often times it becomes commercialized. In that situation only those who are very fervently in respect of the saint can absorb the vibration

The highest of high people like Shirdi , Jalaram, Neem Karoli can maintain their vibrations after they have departed

The peaceful vibrations are still there at Yogananda
