Darkness or Light, which is true?

Every teacher, every prophet, every enlightened person say, 'Light is Truth' and 'Light is Absolute'. Is't so? for me, it's felt that Darkness is True and Absolute. It has existence by itself and hence absolute. One cannot bring darkness to a place, because it's already there. He/She can only bring light to a place, light is 'made', and the moment light goes away, darkness, which is already in existence everywhere, is felt.

Teachers beware!

It's a misconception that

• All web-pages are available indefinitely, without any time limit. This is not always the case. You should check the web site addresses before hand, to see whether they had limited life or still alive, before suggesting them to your students.
• The contents of a webpage do not change. This may put you in trouble, especially links to undesirable web sites are added, after your last visit to the site. Check the page, just before the lesson, and keep watching for a reasonable period of time, as the students may be accessing the page on your advise.
