There are lots of people here on earth who have their third eye, or brow chakra, wide open. There are chakra exercises a person can do to increase the opening of any of their main chakras; these exercises can be found online,
If a person has their third eye wide open, most likely everywhere they look here on earth they will see divine light, in all things and people and surrounding all things and people. In short, in many cases they are consciously flooded with light. It transforms your state of being, but most likely can not be accomplished with an inflated ego.

When you say "attachment", you mean some kind of "unfinished business"? Some mission to accomplish or action to do?

Its' always unfinished business. By "attachment" it is meant by those things we have not let go of. Complete spiritual surrender means being free of all attachments, and just about every religion or spiritual practice talks about surrender or letting go. Most of our attachments are ego based; it is what we hold on to, for better or worst, emotionally and mentally.

And how can one keep Karma balanced? It is really difficult to do this, in one life one can make any good or evil action, such as simple as killing a bug or giving a coin to a beggar. The only way (and it is very difficult to do this) would be to be absolutely isolated from everything, so with this one would not be exposed for any kind of karma (nor good, nor bad). Is there any way to just say "I believe that I don't have any karma debt pending" or something like this and then being free?

Karma is action. What we think, say, and do creates karma, but just thinking you do not have any karma is a kind of self denial. Everyone has karma and we are continually creating more karma. The only way I know of to minimize karma is keep your thoughts quiet as much as possible, do selfless service to others and offer it to God, or the universe, your higher Self, or whatever you may want to call that indescribable divinity. When you speak, let it be kind and loving. Karma Yoga is basically doing humble selfless service to others, especially strangers who are in need of help. This is a good way to loosen the grip of ego and take the focus off of you and place it on something larger or greater. Surrender includes living in the moment with no expectations.
