Thomson Jay Hudson,
The Law of Psychic Phenomena
“ It is universally known to be true, by all who have given the slightest attention to psychological science, that passivity on the part of the subject is the primary condition necessary for the production of any psychic phenomenon. Passivity simply means the suspension of the functions of the objective mind for the time being, for the purpose of allowing the subjective mind to receive impressions and to act upon them. The more perfectly the objective intelligence can be held in abeyance, the more perfectly will the subjective mind perform its functions. ”
