Rooting depends on the ROM, since that's what you root. What rooted Lollipop won't root Marshmallow.

why its like that?

Because you have to add a file to the phone, and you have to be rooted to do it. So someone has to figure out how to get temporary root on a particular phone running a particular version of Android.

Please let me know the procedure how to root again?

Find a Marshmallow root for that phone and your version of Marshmallow. (If you're running 6.0 and root it, then update to 6.0.1, you'll lose root - assuming it'll update at all, which it's not supposed to. When a phone is rooted you can do things to it that will cause updating to hard-brick it.)
