"If you are in love with the moon,
it is because you never stay for long."
The night turned to me and said,
"It is not my fault. I never see the Sun,
how can I know that love is endless?”
In the advancing stages leading to the beginning of the path, the aspirant becomes spiritually prepared for being entrusted with free use of the forces of the inner world of the astral bodies. He may then undertake astral journeys in his astral body, leaving the physical body in sleep or wakefulness. The astral journeys that are taken unconsciously are much less important than those undertaken with full consciousness and as a result of deliberate volition. This implies conscious use of the astral body. Conscious separation of the astral body from the outer vehicle of the gross body has its own value in making the soul feel its distinction from the gross body and in arriving at fuller control of the gross body. One can, at will, put on and take off the external gross body as if it were a cloak, and use the astral body for experiencing the inner world of the astral and for undertaking journeys through it, if and when necessary....The ability to undertake astral journeys therefore involves considerable expansion of one’s scope for experience. It brings opportunities for promoting one’s own spiritual advancement, which begins with the involution of consciousness.Astral projection is one of the Siddhis considered achievable by yoga practitioners through self-disciplined practice. In the epic The Mahabharata Drona leaves his physical body to see if his son is alive.
