(This Chapter is Under Development and Experiencing a Lot of Flux. Stay Tuned!)
1. Mistaking Allegiance to the Guide, Books, or Practices as the end goal of spiritual growth/enlightenment, rather than using them as 'tools' to reach God.
2. Undergoing humiliating practices as a method for 'ego-destruction'. The Ego should fall away naturally over time. The attempt to hasten its departure too abruptly can lead to self-hatred and shame rather than relief.
3. Cutting off contact with 'the outside world'. While periods of isolation/retreat can be extremely useful for calming and intensifying the mind, in a cultic contact it can build a dependence on an 'in-group'. A spiritual practice should also have the goal of lessening suffering in 'the world' whenever possible.
MISTAKING A CHANGE OF COSTUME FOR INNER CHANGE
Here's a short version of how 'conversion' or, if you like, 'cultism' works. If you have found a source of ABSOLUTELY UNQUESTIONABLY BELIEF in some Person, Saint, Messenger, or Book, or God, then for the most part, your SPIRITUAL QUEST is OVER!!
Of course, you most likely don't consider yourself PEFECT in your faith and your actions. But you no longer have any questions as to the Source. The EXTERNAL Source.
Thereafter, your past never has to come up again, because you have been one of the FEW who have come to recognize the Supreme Truth, or had that recognition delivered to you.
