One of the important results you will see from the mandala effects are lessening occurrences. Events that you remember have still happened – just less severe, less horrible, less violent.
The easiest place to notice lessening occurrences is in casualties across history. For example, in the first loop through this changing timestream, over a million people were tortured and burned at the stake over the 400 years of the Spanish inquisition. A few loops later, wiki reported approximately 150.000 executions, and then later only 5000. The same is increasingly true for deaths during world wars and other violent conflicts, instances of racism, rape, murder. On a personal level, if you experienced abuse in your childhood, this abuse may now have happened much less often, and less severely.
With these lessening occurrences, letting go of the old becomes essential.
