Personally, I think, the experience was neither good, nor bad but above such things. Its an astral experience in the physical plane. That is very rare. The light actually materialised in the physical plane and I felt it with my whole body.
I was unprepared for such an experience, so I freaked out. May be I will try it again; this time I wont get traumatised :D
About the mantra: I have observed that there are many mantras in dialects or root syllables that work perfectly. These are all grammatically flawed. How do they work then?
Actually a mantra is simply a vessel of sound that contains the power of the Seer who utters them. If the Seer has power, the mantra performs what it is designed for. Mantras dont work for the doubtful.
Shraddha-vaan Labhate Gyanam = those who have faith attain wisdom.
