Question on rune use

[ohnoitsmook1]

Hello guys, recently I've started using a rune (specifically Lögr) to enhance psychic awareness, but I have a few questions.1 - Am I supposed to meditate on the psychic points after using the rune or does the rune enhance them itself, without me having to work?2 - How long should I use a rune? It's been only 3 or 4 days so far, so I clearly can't expect instant results, but I'm wondering how long I'll need to continue.3 - Does using a different affirmation on one day abrogate the entire working? e.g., if I one day state "psychic centers" but all other days I had stated "astral points" in my affirmation, will I need to start over?4 - Now, when I visualize the Lögr rune, it is pure white in color, though it had been red when I first began using it. Could its change of color mean something?
