Based on the writings of Rav Chaim Cohen, the Chalban, Tallelei Chaim, Sefer Bereishis, P. 532. Just because something is one way today does not mean that it will the same way tomorrow. Trusting in the permanence of the status quo is a mistake. Conversely a person is not permitted to let go to such an extent that he does not engage in any normal hishtadlus (effort) at all. The challenge of acknowledging G-d's presence (which we don't "see") in the face of all physical existence. Taking the sure bet over ruchnius (spirituality) which we don't perceive to be solid and real. What is reality? The illusions of permanence, size and space. Our senses deceive us about the relative wealth ans stability of the physical and spiritual worlds. Finding some good old-fashioned gashmius (physicality) in shul to alleviate the ruchnius (spirituality). Leaving the deal to daven (pray) Minchah means leaving nothingness and entereing into everything. Bitachon is not only for going through a hard time, it is a whole way of life.
