Looking for one’s Bashert is the same as making any life decision.
HASHEM wants us to use this world in the Ways of the World (Derech Ha’Tevah).
And, yet, we are supposed to understand that HASHEM determines every outcome.
We have to do our part, and at the same time know that HASHEM has determined the proper outcome, and He will direct us towards it.
There is a specific system for finding one’s bashert.
Once I have done my part properly, then I have confidence that HASHEM has brought me to the right person, in the right time.
