Think of yourself as an independent being, using the body only as a convenience.

While meditating, ignore the body entirely, and you will find that you will often become almost entirely unconscious of it, and will seem to be out of the body to which you may return when you are through with the exercise.
This is the gist of the Yogi meditative breathing methods, and if persisted in will give one a wonderful sense of the reality of the Soul, and will make him seem almost independent of the body.

The sense of immortality will often come with this increased consciousness, and the person will begin to show signs of spiritual development which will be noticeable to himself and others.

But he must not allow himself to live too much in the upper regions, or to despise his body, for he is here on this plane for a purpose, and he must not neglect his opportunity to gain the experiences necessary to round him out, nor must he fail to respect his body, which is the Temple of the Spirit.
THE UNIVERSAL CONSCIOUSNESS.
The Spirit in man, which is the highest manifestation of his Soul, is a drop in the ocean of Spirit, apparently separate and distinct, but yet really in touch with the ocean itself, and with every other drop in it.

As man unfolds in spiritual consciousness he becomes more and more aware of his relation to the Universal Spirit, or Universal Mind as some term it.
