OM is not where the heart is
The cult member who questions and doubts must be shown to the group to be giving in to his evil, Satanic mind, and not meditating enough, so he or she and the group as a whole will feel the desire to meditate more, and will become increasingly unhappy with their own completely natural, and unharmful thinking processes...
...Visualisation creates a dissatisfaction with material reality and can lead to hallucinations delusions, and nightmares, as the visualised world may come back to mind when you don't want it to. The effect may well be compared to that of the blow back experienced by many people taking hallucinogenic drugs, and some cults may encourage their followers to use drugs as an aid to their visualisations, and/ or give them drugs in food and drinks, without the recruit realising it.
I shall leave the final word with India's finest poet, Radrinth Tagore, and his poem `Against Meditative Knowledge' 'Those who wish to sit, shut their eyes, And meditate to know it the world is true or lies, may do so, it's their choice, but I meanwhile, With hungry eyes that can't he satisfied Shall take a look at the world in broad daylight".
ITS ALL IN THE MIND - A FURTHER CRITICAL ATTACK ON MEDITATION.
..."An undisciplined mind expresses evil thoughts by evil actions, and these actions leave evil after-effects on the mind: and as soon as external stimulation occur, the mind suffers the consequences of its past actions. Thus, if we suffer miseries, they have their remote cause: in the past. All pleasures and pains have their mental origins; and religions are required because without them, the mind cannot be controlled."
Not surprisingly, the author tells of how the adept experiences `tremendous physical pain' as 'he or she seeks a cessation of all mental processes'.
The mind is basically seen in Eastern belief systems as a barrier between us and the absolute:
...Birds should be alarmed if their cages are disturbed, Dr Dace, and so should the mind if it faces some data of which it is (at least temporarily) uncertain. Desensitising the mind to stimuli may actually affect human ability to react properly with the level of fear, love and other emotions required in any given social situation. Dr Dace argues that we ought to hear from people who have practised meditation techniques before making up our minds. I practised four visualisation meditations solidly between 1981 and 1985 see THE BRAINWASHED SKEPTIC article for the full story of my cult involvement)
