A week.

Ordinarily I would think it should take a bit longer, but a week may be long enough.

The little crystals may have only been a catalyst... we can consider the placebo effect in conjunction with a kind of synchronicity. I've noticed that almost any solid manifestation of spiritual commitment is followed by a response from the Other Side. Efforts are rewarded.

But, yes, more often I would expect about two weeks to be enough time for the Higher Mind and all of the Spiritual Resources to assemble an adequate Presentation.

Yet, many Yogic Traditions that use the power of Shaktiput -- transferring Spiritual Energy by touch -- may adapt the method of touch to one of transfer through a retentive material. I knew a Guru who would put the Shakti into glasses of water. Putting the shakti into little stones is fairly similar enough.

Yet, there are Buddhists and there are Buddhists. Much of popular Buddhism is not much different from native shamimism. Notice that the dreams were not all that enlightened. One must consider whether the power passed to one is entirely Free and Spiritual or whether it comes with a spell or a charm or even a curse. Consider that many of the Tantric Buddhist Disciplines are motivated by a competitive and macho formation of attitudes. It would not be beyond these people to engage in practices of Spiritual Cannabalism. I once read a fairly scarey treatise on Spiritual Cannabalism that came out of the Tantric Buddhist foot hills of the Indus Subcontinent. To them it is all about whoever scores the most points, wins. In the West it is all about money. In those hills it may be all about spiritual conquest, not of Self, but of others.

I have had dreams in which I have put out my hand, and my enemies began to shake uncontrollably. Touching them was the final blow. I would not want to have a dream in which I was the one who was made to shake uncontrollably.
