If unsolicited advice is well-intentioned and done in the highest and best way from a vantage point of acting through good intentions backed by inner wisdom gained from life experience, one is simply doing one’s best to prevent a mistake of some kind and in the doing, help someone else avoid inconvenience or failure. If it is done to reward the ego, this is not a lofty intention. Even though it might help save the day in other respects, the true analysis of what is taking place will reveal that there are mixed energies in play and those benefits will not be returned to the individual as a blessing because it was self‑serving to begin with and the person, as a consequence, is not deserving of a reward.
In this example, the more experienced student inserting his advice that was rebuffed failed to fully warn the overconfident beginner that he would create a mess when there clearly was ample time to insert that useful piece of information in the exchange, but instead simply gave instructions and then waited to see what would happen. Seeing that haughty individual who was overconfident of his ability receive a dousing of oil and be laughed at was a predictable consequence, so the intention initially to be helpful became perverted by the withdrawal of complete information as to what might happen and in this case, reveals there was a mixed agenda in play.
So the Law of Karma would see this for what it truly was, a vocal display of superior knowledge to put the person in a position of then saying, “I told you so but you didn’t listen,” as a way of rubbing in the harsh lesson to the other party who failed to follow the advice, but could have been saved from making the mistake and the subsequent embarrassment, so it did become almost an act of bullying. The fact that the haughty novice ignored the advice as it was being given is a mitigating factor for staying silent about what was about to unfold, but it does not remove all culpability from being of service when it was possible to do at no real cost in giving a fuller description of what was about to happen.
