Although on the path toward spiritual perfection, one is not usually urged to immediately adapt to the loftiest levels, the Alter of Novardok in Madreigas Ha’adam advises one to do this with bitachon, since bitachon is an exception to the rule. 

Since one’s level of bitachon and reliance on Hashem results in Divine blessings that correspond to the depth of his convictions, the best thing is to start at the top, as this way, he will immediately see the beauty of true bitachon and will have an easier time sustaining this exalted level.

Conversely, when someone starts slowly from the bottom up, he will see only blessings corresponding to his lesser efforts, so his climb will be more difficult.

Therefore, go all in! Rely on Hashem completely and see the results!
