I would say, those enlightened sadhus did not any luxuries of life. They were all eternally in absolute bliss that can't be matched even by the most extravagantly living man in the world.
There is this confirmed misconception that those whose life is in the transition stage-from materialistic to spiritualistic, always face financial shortage.
Well, they can enjoy the highest pleasures without having to spend a dime. They just could create anything out of thin air but only they never felt the need.
I firmly believe that the so called spiritual powers were gifted to them from the universe. They mostly would not have spent a fortune to get these healing powers like medical practitioners. So, it is quite possible that they believed in giving things away freely that were given to them freely.
