The experiences of the subtle sphere by one on the subtle planes are continuous, but even these experiences are of illusion, for Reality is beyond them. And so, though LSD may lead one to feel a better man personally, the feeling of having a glimpse of Reality may not only lull one into a false security but also will in the end derange one's mind. Although LSD is not an addiction-forming drug one can become attached to the experiences arising from its use and one gets tempted to use it in increasing doses, again and again, in the hope of deeper and deeper experiences. But eventually this causes madness or death.
“An example of experiences that are shadows of the subtle plane encountered in the gross world is that of a yogi who taught his 150 students to go into trance. When the students came out of the trance they were asked by the yogi to describe their experiences. Their accounts would be amazing to a man in the street, for in their state of trance they saw lights and colours galore — dazzling lights in colours and in circles and in different designs. They felt all things around them pulsating with life and felt themselves separate from their own bodies and become witness to all things.
"Even such experiences as these are but the shadows of the subtle plane experienced in the gross world, for they are not continuous. However, these are NOT spiritually harmful, but neither are they spiritually beneficial. But experiences induced through the use of drugs are harmful physically.
"Even actual experiences of the subtle planes in the subtle sphere (which are always continuous) are likened to the pleasure of children playing with toys. However, these experiences are spiritually beneficial since they create a longing in the aspirant for further advancement. But union with God is impossible without the grace of the Perfect Master.
"Consciousness is fully evolved and complete as soon as the soul identifies itself with the human form. This consciousness neither increases nor decreases; only the experiences of consciousness increase. Hence the states of sub-sub super consciousness, sub-super consciousness, super consciousness, sub-super consciousness, super consciousness and God consciousness. This in other words is gross consciousness, subtle consciousness, mental consciousness and God consciousness. The lighter the burden of impressions (sanskaras) the higher the experiences of consciousness.
"There is also a state of perverted consciousness. It is a state in which consciousness indulges in induced experiences such as those gotten from the use of drugs; and even the most fantastic experiences thus induced are only the shadows of the subtle plane experienced in the gross world.
"Only the One who knows and experiences Reality, who is Reality, has the ability and authority to point out the false from the Real.
