Acharya Prashant explains that when one starts getting success on a particular path, an excitement arises which seems to be a supporter of progress but is actually intent on blocking it. The correct response when something is going right is to simply put your head down and continue doing what you are doing. Many people let valuable things slip away because they take them for granted. Once you receive something valuable, it becomes your duty to stop looking elsewhere and to serve what you have without deviation or question. The speaker uses an analogy of medicine to illustrate this point. If a medicine is benefiting you, it is best to complete the full course. Many people suffer precisely because a medicine is so effective that it shows results quickly, leading them to discontinue it prematurely. For example, a medicine prescribed for six months might show improvement beyond expectation in just two months, causing the person to stop taking it. This is how the ego works; the very success of the medicine leads to its discontinuation. Similarly, a child with a fever might be prescribed medicine for ten days, but if the fever subsides in three, the child may refuse to continue. The fever can then return as a chronic issue, requiring a much longer course of treatment because the original case was spoiled. This pattern applies to the spiritual path. One might engage in a little spiritual practice (Sadhana) and receive results that seem disproportionately large. This can lead the ego to believe it has 'got it' and become complacent. The speaker advises that one is not entitled to a firm conviction of Truth after a short time and with little investment; expecting so is a function of the ego. Spiritual practice must be continuous, uninterrupted, and unquestioned. One should not ask when they will gain a firm conviction of Truth, because Truth is not a conviction or something one can possess. Instead, Truth possesses you; you are never going to 'have' the Truth.
