Type of Spiritual Experience
A description of the experience
I begin by stopping all reasoning, and I throw all my inner power into perception of spiritual sensation. I affirm that this condition is brought about by my unshakable faith in the spiritual unity of all humanity I then find myself in a new and special state in which I see and hear outside time and space.
Whether I am reading a sealed letter, or finding a lost object, or psychometrizing, the sensations are nearly the same. I seem to lose some energy; my temperature becomes febrile, and the heartbeats unequal.
I am confirmed in this supposition because, as soon as I cease from reasoning, something like electricity flows through my extremities for a few seconds. This lasts a moment only, and then lucidity takes possession of me, pictures arise, usually from the past.
I see the man who wrote the letter and I know what he wrote. I see the object at the moment of its loss, with details of the event, or again I perceive or feel the history of the thing I am holding in my hands. The vision is misty and needs great tension. Considerable effort is required to perceive some details and conditions of the scenes presented.
The lucid state sometimes arises in a few minutes, and sometimes it takes hours of waiting. This largely depends on the surroundings; scepticism, incredulity, or even attention, too much concentrated on my person, paralyses quick success in reading or sensations
