Every religious person has a moment or a time in life when he has some awakening from above, where he feels vitality about being Jewish.
In general, one is in several states where he has no grace of Kedusha [holiness], and sometimes altogether forgets that there is Kedusha in the world. Even when he remembers, it is only due to upbringing, meaning habit, such as when he blesses the blessing over pleasure. Sometimes, he does not even feel to whom he is speaking or what he is saying, and the blessing he said is only out of habit.
Yet, sometimes in life, a person does feel vitality in Kedusha. This can be for a short while, such as a minute of feeling the flavor of Kedusha, which comes to him by an awakening from above, and a person can awaken a Reshimo [recollection] from this, that once he had an awakening.
It therefore follows that every person has within him a Reshimo, and that Reshimo contains the Kli [vessel], meaning the heart, and by this, one can make an awakening from below.
