Readers will better understand certain perspectives of the lectures published in this volume if they keep in mind that the Teaching of Master Omraam Mikhaël Aïvanhov was strictly oral and that the publishers have made every effort to respect the taste and style of each lecture. The Teaching of the Master is more than a body of doctrines: it is an organic whole, and the way it is presented is to approach it from countless different perspectives. By addressing certain perspectives on many different subjects, it constantly reveals a new dimension of the whole, while at the same time shedding new light on the individual aspects and vital connections between them.
