How to Dissociate From Body-Consciousness?

In order to overcome the confusion between the narrow lower self and the Real Self, in the state of meditation visualize that you and your body are two separate entities and you are using your body as your garment or a tool. Try to understand your body as you consider your garments. Visualize that your "I" would continue to exist even after the body has been discarded. Conceptually leaving the body, look at it from a higher level. Look at the body as though it were a hollow nest, in which you live and could easily come out of it. Consider yourself as the caretaker of this house, who is responsible for its sanitation (keeping it pure in thoughts and deeds), strength (keeping it strong) and functionality (physical activity). You are the master of the body and are using it as per your own free will. In this way, conceive: "I" am not this body. It is only My tool. "I" am using it only as a rest house. This body is built up with five basic elements of nature collected by "ME" (my real self) for giving it a desired appearance. (Scriptures tell that soul acquires a body and environment conforming to the traits brought forward from previous births i. e. the inherent traits from previous births are the building blocks of the mind and body of the new born.) During meditation, totally forget about your body and concentrate your thoughts and emotions on "I" as an independent conscious entity. Then you will become aware that the soul has an immortal existence independent of the body. Having had this awareness, whenever you will say "I", this expression will have an altogether a new meaning for you.
(However, it does not mean that you are required to ignore your body. Doing so will be disastrous. Considering body as the temple of soul it is your solemn duty to protect it in every way and keep it healthy and strong).
Paranormal visions and experiences
In the initial stages of Sadhana, the foregoing practice of dissociation from body-consciousness remains an entertaining and relaxing exercise, but as this imagery begins to take roods, the practitioner may feel as though he had actually died and may have such visions which one has at the time of death. There may be flashes of paranormal visions of those things, which are not physically visible at the place of meditation through normal sight. Hazy images of the extra-sensory world (sookshma Jagat) may be seen. Many other-worldly forms and heavenly scenes may appear. It may frighten the beginners, though there is nothing to be afraid of. Sometimes acceleration in the process of Sadhana, because of virtuous traits brought forward from the previous births and latent memories stored in the deeper levels of consciousness (also from previous births) become suddenly activated. This acceleration uplifts the mind to higher dimensions of awareness. With the passage of time, the Sadhak gradually becomes accustomed to paranormal experiences and such occurrences no more surprise of frighten him. With steady progress, the seeker acquires the capability to dissociate the soul from the body at will which, rising beyond the body, becomes aware of phenomena beyond physical sense perception. In this state, however, the soul of the practitioner does not actually leave the body but, like a person sticking out his neck out of a window to look outside and then withdrawing it at will, is able to transcend the limits of the body, without serving connection with it.
The beginners are advised not to be in a hurry to have occult and paranormal visions and experiences. It would tantamount to violating the natural process of gradual spiritual advancement. In due course, worthy seekers will be initiated into the technique of accessing the domains of paranormal visions (Paroksha Darshan). Here a passing reference to such experiences is considered necessary, so that when such visions do appear the Sadhak does not get frightened or nervous.
