How shall a man guard himself from the dangers of the wrong use of thought substance?
“First and foremost, by the constant practice of Harmlessness. This involves harmlessness in speech and also in thought and consequently in action. It is a positive harmlessness, involving constant activity and watchfulness; it is not a negative and fluidic tolerance.”
~ Alice A. Bailey, 1880-1949, Theosophist and Author on Esoteric Spirituality
