Most of us have learned in childhood that we live on earth and God lives in heaven, and that the two are always separated. In reality heaven and earth exist simultaneously, in the same location, they are simply of different vibrational frequencies.
When we practice meditation we eventually connect with our Higher Self, or our higher mind, also called our wise mind. As we open ourselves to our higher Self we receive the guidance and assistance we need (even though it might not always be what we want). The connection with our Higher self allows for the unification of intuitive levels at our lower, concrete or logical mind. This is the first step toward soul connection, our Divine Self.
In our present time we have the possibility to develop our mind more than ever before. It opens us not only to intuition but to the possibility of illumination. This is reaching heaven.
