Hashem has commanded us to perform the mitzvah of hishtadlus, making an effort, whilst at the same time it is of paramount importance to internalize that the effort that we make has zero impact on our desired results, to the point that if we do believe that we are contributing and helping Hashem in any way, that could borderline on the grave sin of idol worship. Emunah and bitachon are like a muscle. Just like with a muscle, the more we work it, the stronger it gets, but we can't go too fast because we can damage the muscle if we don't build it up slowly. In the same way with emunah and bitachon, the more we internalize the concepts and practice our bitachon in Hashem, the more our emunah and bitachon muscle will grow stronger.   Because hishtadlus can be such a dangerous deterrent to internalizing the truth of emunah that Hashem runs the world exclusively, as we grow our emunah and bitachon muscle, there might be certain times that it would be appropriate for us to exercise our bitachon muscle in a particular situation. If after having learned about the topic and having seeked Torah guidance, Da'as Torah, and also having davened to Hashem to guide me to find the right level of hishtadlus that would be appropriate for me in my particular situation, let's say I am looking for a spouse and the way I would like to do so is by calling a shadchan, a matchmaker. If I have decided that it would be appropriate for me to call five different shadchanim because each one is exposed to a different community and could have different options as a potential spouse for me. At times, it might be appropriate to say, “I've been learning about emunah and bitachon and I feel that in order to exercise my bitachon muscle, it might be appropriate to only call four shadchanim today as opposed to five. I'm going to minimize the hishtadlus slightly.” Of course, this needs to be done very carefully and according to Torah guidance and through prayer to Hashem, but it is important to remember that bitachon is a muscle and the more we work it slowly and carefully, the muscle grows and we will excel in our reliance on Hashem.   It is also worthwhile to point out the famous idea that Rav Dessler brings down in the name of the Baal Shem Tov, that everything Hashem created has a place to use both for the good and also for the bad. So, for example, one's eyes one can use to learn Torah, to make a facial expression to make somebody else happy and the like, that would be a mitzvah. And in the same way, if one views inappropriate material, that would be using the gift of one's eyes in an inappropriate manner. And they point out that every character trait can be used in both the service of Hashem for the good as well as for the negative. Usually, it is not a good thing to raise one's voice and shout at another individual, and that often would qualify as a sin. However, if somebody is about to get hit by a car and you shout at them to get out of the road, thereby saving their life, that would be a time where exercising the character trait of shout and panic would be appropriate and a mitzvah.   When it comes to the character trait of kefirah, which means denial of Hashem, how does one use denial of Hashem in service of Hashem? And they point out that when it comes to our own selves, our own lives, that is when we should do our best to grow in our emunah, our bitachon, and make our maximum effort to build our bitachon muscle. However, when it comes to the lives of other people, that is not our place anymore, to accept the situation with emunah and bitachon. From our viewpoint towards another individual's life, when they have a need, we are not to have bitachon and exercise our bitachon muscle, but rather that is the time to exercise our character trait of kefirah, of denial of Hashem, and in a sense say, “you need something? Let me see what I can actually do for you.” It is not a time to say, I'm sure Hashem will come through for you. It is important to dis
