Question: Can we reach mutual guarantee (Arvut) before or after impregnation (Ibur)?

Answer: Arvut is a necessary condition for the conception of the embryo but specifically in conditions in which we currently find ourselves.

At every moment we are in different states and we must work on nullifying ourselves before our friends and connecting with others in mutual support. This state is called mutual guarantee (Arvut), meaning mutual guarantee and mutual support.
