The seventh dimension is often called the soul plane because it is the true dwelling place of the soul.
It is here that eternity begins.
Without beginning and without end, the sea of love extends throughout the Universe, calling on all to join in unity and oneness.
In the seventh dimension there is no longer an ego or personality.
There is a single Self, a single soul, immersed in a world of dancing, vibrating light and pure consciousness.
There is still a "you" and "me" but there is no sense of separation.
Everything is connected to everything else.
While the soul can merge with other souls, and often does, it remains a complete, unique reality unto itself, a holographic image of God.
In this realm, the pure essence, Higher Self or soul (whichever term you choose) evolves into a greater and greater universe of its own, eventually learning how to create entire new universes.
The fully evolved soul can create infinite varieties of life forms, each a holographic representation of itself.
The seventh dimension is the beginning of the true heavenly realms.
The seventh dimension is also a level of supreme intelligence and wisdom; an inexhaustible storehouse of knowledge that guides every soul on its journey through eternity.
