First and foremost be careful that every motion in the Divine service be
without ulterior motives, Heaven forbid. 1 This requires profound wisdom “exceedingly deep, who can find
it out?” (Ecclesiastes 7:24) There is then no alternative but to retain
constant awareness of this principle. Do not divert your mind from it, even for
a moment, for it is a matter that is flawed by distraction.
Secondly, you must also be scrupulous with [ritual] immersion, and to
concentrate in the mikveh on the appropriate kavanot (devotions)
for mikveh. 2
For the “three-fold cord that is not broken quickly” (Ecclesiastes 4:12):
remove yourself from depression and let your heart rejoice in God.
