I believe u do not even rub up past a stranger walking by in the street without some of thier energies rubbing off on u. . I think it is always good to keep up ur daily meditations, keep ur shakra's open and balanced so that your's is a positive energy that is given off and that not too much of others negative energies given to u. As for interacting with others . .absolutly there are many lessons and guidence's that are shared. . . . The big spiritual dilema i have is wen u have a seriosly negative person whom ur interating with how much time to spend in thier precence. . How much of thier negative can u assorb before u have left them with smthing positive.. . We always hear that we shud walk away and dont let thier negative attitude effect us. . But how will thier negatives be changed if all us stronger ppl keep on ignoreing them bearing in mind that not all of us are mentaly strong and need a gentle loving prod at times . . Mm thats a tough one. I like to make sm kind of enecouraing statement and leave it at that before leaving so that the last departing influence u've made is a lasting positive one. . .then as u walk away u silently pray that it will stick to them. Blessings laughtr and abundence to all who read this.
