"and anyone who does touch a woman other than his wife brings death to himself.' says the Ramchal- just as a Nazarite- a person who made a vow to become a Nazarite and not drink wine says the Torah, not only is he not permitted to drink wine, but anything that pertains to wine is prohibited as well- all of this is included in the prohibition- for ex: fresh grapes, dried grapes (raisins) or after they squeeze the grapes and soak them in water and then squeeze them again there's still a taste of wine in the water- this is also prohibited for him to drink. anything having to do with grapes he must stay away from as that is all included in the prohibition. same thing as when the Torah prohibited a woman that does not belong to you, meaning- a woman that he did not sanctify under the wedding canopy- unlike today when people think that if two people decide to be friends, it's as if they've connected to one another in some way, as long as there is no sanctification under a wedding canopy, where he gives her a ring and says" Behold you are consecrated to me with this ring according to the laws of Moshe and Israel" and they stand under the canopy and recite the seven blessings, together with the ritual bath that she immerses herself in to be holy to him- as long as it is not done so, there's no real connection between the roots of the two souls from above.
