I started to practice Dorje Shugden about 4 years ago, it was started because I visited on of my friend's Buddhist centre where I met this wonderful statue of Dorje Shugden on the main altar. Back then, I have no idea who Dorje Shugden is, all I know is just Buddha Shakyamuni, but I just got so attracted by Dorje Shugden statue, which on the same day I requested my friend to teach me his mantra.
I still remember my grandma was very sick and she was suffered with lung cancer that time, she need to go through tremedous pain and short of breath every single day and I pray to Dorje Shugden and requested him to help my grandma in whatever way he can, just to reduce her suffering, and I started to chat DS mantra every single day. About a week or 10 days later my grandma pass away still but when the last 2-3 days of her life, she was totally better, her pain reduce and she feel better and she passed away in not much suffering.
Do I have proof Dorje Shugden really help my grandma ? I don't but I do believe because of DS's blessing my grandma doesn't need to go through horrible death. Since then, I reciting Dorje Shugden's mantra everyday and later started to do his daily prayer.
Well, this is a short story how I started my Dorje Shugden practice
This is the prayer that I found on here, which very similar to what I have been doing, hope it will help people who are in difficulty too.
