The Hidden Power and Other Papers Upon Mental Science 

‚To realise fully how much of our present daily life consists in symbols is to find the answer to the old, old question, What is Truth? and in the degree in which we begin to recognise this we begin to approach Truth. The realisation of Truth consists in the ability to translate symbols, whether natural or conventional, into their equivalents; and the root of all the errors of mankind consists in the inability to do this, and in maintaining that the symbol has nothing behind it. The great duty incumbent on all who have attained to this knowledge is to impress upon their fellow men that there is an inner side to things, and that until this inner side is known, the things themselves are not known.‘ So begins ‚The Hidden Power and Other Papers‘, a collection of lectures and papers by Thomas Troward on various subjects.
