My personal opinion -after having met many such characters- in India; either in Varanasi, Rishikesh, Vrindavan et al, as well as at the Kumbh Mela, is that the majority of them are fake in the sense that they're not dedicated ascetics, but individuals who are adopted a vagabondage lifestyle, begging for alms and food...under the guise of being holy and religious.
The setting for the photo shoot which resulted in the slideshow was the beautiful Lin Ben Yuan Family Mansion and Garden (林本源園邸) in the Banqiao District, Taipei. It was a residence built by the Lin Ben Yuan Family, and is the country's most complete surviving example of traditional Chinese garden architecture. It can be traced back to 1847 when it was built for storing of rice crop whose location was more convenient for the increasingly wealthy Lin Ben Yuan family. A few years later, it became the family's main residence.
