This series of the twelve disciples we will explore Thomas the doubter..
The seventh is called Thomas. This disciplined quality doubts or denies every rumor and suggestion that are not in harmony with that which Simon Peter has been commanded to let enter.
The man who is conscious of being healthy… (not because of inherited health, diets or climate, but because he is awakened and knows the st ate of consciousness in which he lives) … will, in spite of the conditions of the world, continue to express health. He could hear through the press, radio and wise men of the world that a plague was sweeping the earth and yet he would remain unmoved and unimpressed.
Thomas, the doubter when disciplined would deny that sickness or anything else which was not in sympathy with the consciousness to which he belonged had any power to affect him.
This quality of denial when disciplined protects man from receiving impressions that are not in harmony with his nature.
He adopts an attitude of total indifference to all suggestions that are foreign to that which he desires to express. Disciplined denial is not a fight or a struggle but total indifference.
