An affectionate disposition...
"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."- His Holiness the Dalai Lama
