Does one fall in love when he is m’kayim “Love thy neighbor as thy self”? Learn the meforshim before commenting on Yaakov’s love for Rachol. “
Perhaps I misunderstood the point of your post. There is a difference between v’ahavta L’ Rayacha, as opposed to Vaye’ehav Yaakov ES Rachel. It does not say V’ahavta ES rayacha. The ES, in my opinion, shows an added dimension to the love one should normally feel for his fellow man (as in the V’ahavta l’rayacha phrase) a dimension that applies to the love of one’s soul mate.
Yaakov’s love for Rachel was instantaneous, he knew she was his basherte, and the Torah clearly defines how strong his love was for her, to the extent that he was willing to wait seven years in virtual indentured servitude to marry her, and then an additional seven years after being allowed to marry her, to “pay off” his shver for that privilege. That, is immeasurable love. It is not the same thing as the love we are commanded to show all mankind.
