Significance of Saffron Colour in Hinduism

[Guest guest]

Namaste,

I wanted to know why is the Saffron (Bhagavaa) colour considered sacred? Why was it chosen to be the colour of Hinduism?

Also in one of your replies to a post on Ghosts and re incarnation you mentioned that if people commit suicide they turn into ghosts? So is it that only people who commit suicide or who die in an accident become ghosts? Are ghosts only evil in nature or can there be good ghosts as well? Also you said that when we die at our prescribed time of death the new body is ready for us...but what when some people prolong their death due to either medication or say due to some good practises like yoga etc. what happens to the bodies already ready for them?
