Lecture I
From this point of view it will sometimes be necessary to meet our explanations with a certain amount of good-will; for were I to bring forward all that might be adduced in the way of evidence and proof of what will be said here in the next few days, it would require a much longer time. We should not advance in our knowledge of this particular subject, if we were not to make some little appeal to your goodwill and sympathetic spiritual understanding. For indeed the province which we touch upon here, is one which up to our own times has been more or less avoided by occultists, mystics and theosophists, for the reason, that a higher degree of open-mindedness is necessary, in order to accept the things that are to be said, without a certain degree of opposition that might now and then be felt.
