This material world has an outward appearance, as it has also an inner reality. All created things are interlinked in a chain leading to spirituality and ultimately ending in abstract realities. I hope that these spiritual links will become stronger day by day and that this communication of hearts, which is termed inspiration, will continue. When this connection exists, bodily separation is not important; this condition is beyond the world of words and above all description.
