The need for miracles means that the vital wants an easy way out. It means that we are wanting the Divine not for our ultimate and permanent good but for the satisfaction of desires and for transient good. Perhaps that is why the miracles have become less so that one can graduate from the artharthi (seeker of material goods) to a jigyasu (seeker of Knowledge and Truth). It means that the Mother is taking you seriously and wants you to engage with the yoga in a true way. The first step to be taken is to read Her works so that we know that the true miracle is not getting what we want but becoming what we must be. Do not lament the past but learning the lessons go forward confidently towards the future.
Affectionately,
