Inflamed with all kinds of horrible appetites which they can no longer satisfy directly now they are without a physical body, they gratify their loathsome passions vicariously through a medium or any sensitive person whom they can obsess; and they take a devilish delight in using all the arts of delusion which the astral plane puts in their power in order to lead others into the same excesses which have proved so fatal to themselves. Quoting again from the same letter:--"These are the Pisachas the _incubi_ and _succubae_ of mediaeval writers--demons of thirst and gluttony, of lust and avarice, of intensified craft, wickedness and cruelty, provoking their victims to horrible crimes, and revelling in their commission". From this class and the last are drawn the tempters--the devils of ecclesiastical literature; but their power fails utterly before purity of mind and purpose; they can do nothing with a man unless he has first encouraged in himself the vices into which they seek to draw him. One whose psychic sight has been opened will often see crowds of these unfortunate creatures hanging round butchers' shops, public-houses, or other even more disreputable places--wherever the gross influences in which they delight are to be found, and where they encounter men and women still in the flesh who are like-minded with themselves. For such an entity as one of these to meet with a medium with whom he is in affinity is indeed a terrible misfortune; not only does it enable him to prolong enormously his dreadful life in Kamaloka but it renews for perhaps an indefinite period his power to generate evil Karma, and so prepare for himself a future incarnation of the most degraded character, besides running the risk of losing a large portion or even the whole of the lower Manas. On this lowest level of the astral plane he must stay at least as long as his earthly life would have lasted if it had not been prematurely cut short; and if he is fortunate enough _not_ to meet with a sensitive through whom his passions can be vicariously gratified, the unfulfilled desires will gradually burn themselves out, and the suffering caused in the process will probably go far towards working off the evil Karma of the past life. The position of the suicide is further complicated by the fact that his rash act has enormously diminished the power of the higher Ego to withdraw its lower portion into itself, and therefore has exposed him to manifold and great additional dangers: but it must be remembered that the guilt of suicide differs considerably according to its circumstances, from the morally blameless act of Seneca or Socrates through all degrees down to the heinous crime of the wretch who takes his own life in order to escape from the entanglements into which his villainy has brought him, and of course the position after death varies accordingly.
