Is lust the feeling of an empty mind?

Can a joyous and happy mind generate lustful feelings?

It is difficult to undeerstand the topic! Can you word it differently?

The very word lustful has many meanings. it means joy, pleasure, craving..[need not mean only sex]. Except peace, lust is inter-related with the rest..i think.

Exactly!

Sorry for the confusion.

Lust is essentially a feeling / emotion that co exists with many of its kind like greed, jealousy and anger. When used in the right measure and for the right reasons this could act as a catalyst viz as lust in the correct measure could provide you the thrill in matrimony, moderate jealousy and greed could make you ambitious and growth orientated likewise anger could help you to fight injustice. A lot depends on the kind of tutelage you have been under and the value systems you inherited.
