hi mchan dushan,
he actually lives close to my house..i dont kno him in person bt i have seen loads of his patients on the road after treatment covered their eyes with herbals n stuff..he lives in Gangula, Panadura..hence the name gangule weda mahaththaya i presume..u just gotta cm to Panadura, turn left to Hirana road (thats the big road to ur left infront of panadura hospital/police junction, wont be hard to find), cm another Km or so on that road without making any turns and u'll pass a temple on to ur right..juz ask anyone from that area n they shud be able to direct u to him..im a doctor my self n i have no experience in ayurvedic medicine..so i cnt comment on wat others here r talking about..i hope this helps
