An affectionate disposition not only makes the mind more peaceful
and calm, but it affects our body in a positive way too. On the
other hand, hatred, jealousy and fear upset our peace of mind, make
us agitated and affect our body adversely. Even our body needs peace
of mind and is not suited to agitation. This shows that an
appreciation for peace of mind is in our blood.
Jealousy in romance is like salt in food. A little can enhance the savor, but too much can spoil the pleasure and, under certain circumstances, can be life-threatening.
Love shouldn't be about jealousy or anything like that. It should be about commitment and being able to trust that person. If you can't have that from the get-go, there's a problem.
