Most of the modern logical minds are ready to accept the need of a coach and controlled environment of learning when it comes to various other practical subjects (biology, nuclear sciences, diving, paratrooping and other sports etc.) but the same people seem to shrug their shoulders vehemently when the same rule is said to be in following elsewhere especially the ancient occult-spiritual methods.
Tantra is a discipline which is transmitted only through the lineage or Guru-Shishya Parampara. The sanctity of books is not doubted however the only things one should experiment with is only when he/she is told to do so. It is so because there are so many things which have been kept secret in these books and are received only through an adept of the subject. I am saying this with my own experience of the subject.
So if you are not following the basic rule of receiving these spiritual or occult sciences through the Master-Disciple way – whatever the subject or title of the book be, it is most likely to fail you or even harm you.
Finally, despite all these words from me you can still engage in any of the practices for your amusement and amazement. No one can stop you🙂
