hmm...i too have had this experience, mostly purple  and white but what im really interested in is everytime i close my eyes ever since i was a little girl i saw these black and white spiralling...things. Its just like black whirling "blankets" (as my friend called them because she sees them too) and then a white one will come and join...its hella weird. Does anyone have any information on this? I didnt want to start another thread because theres not enough for me too say so im hoping this thread was okay to intervene in.
Also i was wondering about something else. I know someone who says that when she closes her eyes she sees an eyeball in the corner of her eye and when i was younger i used to see this. Is it just seeing a "reflection" of your eye or what?

Carpe Noctum

In my opinion, we can see different lights if we need to clean and fill any ernergy center with prana (or qi). Seeing a lights is very individual and we dont have to concentrate on that. When all centers are optimized we can feel unity with all universe and we cant describe a special light... all is beutiful and joyful

my light always color purple, green, and orange but lastly the purple dominating... the green is in the centre and the orange perish , i never see it again.
a little bit confuse... i see these colors after practice meditation for about 6 months...
i ask my friends who already practice meditation for years and he is just wonder about that...
he said that not so many people reach this light in six months time of meditation

while do meditation itself, i never learn the right technique... just sit in the comfortable position and close my eyes... and never now the stage of meditation
i'm starting meditation to reach good health as  i know from some  health journals that meditation increase serotonin in the brain
i let my mind free from any thought

in the past about 3 months ago i saw the light always white and very bright
and now change to be more colorful and i always find that i feel deep peace everytime this light come to me

and wanna ask is the light really dangerous as someone posted here?
