Affection.....

Everyone can understand from natural experience and common sense 

that affection is crucial from the day of birth; it is the basis of life. 

The very survival of our body requires the affection of others,

to whom we also respond with affection.

 Though mixed with attachment, 

this affection is not based on physical or sexual attraction,

 so it can be extended to all living beings without bias.

~Dalai Lama
