[Excerpt from Michael Speaks -- April 2008 (Platforms)]
We will first define "Platforms" as "a focus for experience from an Essence Level." We can define this word in several ways, but this will suffice here. It is important to note that the Platform is an Essence-level focus, and not necessarily something that will be obvious to the Personality, though the Older the soul, the more likely the Platform will be obvious. The Platform can be understood as a pattern or theme of experiences that are of interest to the Essence, but Personality can always override this, or ignore that interest altogether. It is called a "Platform" as it is almost literally a higher perspective of the life, which is often why the Platform is more obvious in retrospect to the Personality than it is during the actual time period of that Platform. Knowing your Platform for any given period of time can help bring conscious alignment with Essence, if you choose to work on this experience. Platforms are not imposed or assigned. There will always be at least one version of you in one parallel who will find it interesting to bring Essence into the life, so to speak, but in parallels where Essence is resisted, ignored, or restricted, the experiences are just as valid and of benefit to Essence in the end. Some of the ideas and choices of Personality would never occur to Essence, which is why Personality is given such free reign. And many of you already know that many of the choices of Essence might never have been chosen by you as a Personality; often this is met with a "what the hell was I thinking??" commentary to Essence. We point this out to make it clear that Essence and Personality can work together or separately, and that choice is yours as Personality. When we say "separately," it is not literal, because there can never be a true separation, but we use the word appropriately. To pay attention to your Platform is to pay attention to Essence. To pay attention to Essence is to help generate True Personality. To generate True Personality is to live the life without unwarranted fears. And so on. ...
Keep in mind that when one considers the Platform as it is described, there will also run alongside that Platform its polarity, or "opposite" as a means to explore the entirety of the experience. If we describe your Platform with the word TRUE in front of the phrase or word, this means we see this as a pivotal year of potential for truly "getting it' in terms of that Platform. This would mean you have visited this Platform several times already within the life.
[Excerpt from OMW - June 14, 2013 - Getting the Most Out of Your Platform]
Platforms come on a fairly regular basis in cycles that last between May of one year to April of the next. This cycle is based on precedence set long ago in the species relative to the seasons.
There is a Platform for each of you based in 100-year cycles, as well, and one for the entire species/Design, as well.
