I enjoy discussing Buddha Dhamma, Thai Buddhist amulets (especially Phra Pidta), and Gathas. FYI, I have been Samanera for 4 times (2 Thai tradition under LP Meechai; 2 Sri Lankan Tradition in Buddhist Maha Vihara). Currently, I'm wearing the Phra Pidta (Ajarn Thong Susangwaro) only. I believe that if one amulet is working, no need to wear too much. *Last time, I used to carry 3, until a monk advised me one also can if properly consecrated by Ajarn/LP with highly developed Dhamma skills and wichah.
