Absence of Emotions

Can we lose the ability to have simple emotions.Is emotional deadening a mark of a evolved person.Most of the religious/spiritual books do tell us how everything related to emotion is useless.Our jealousy,pride,sadness or happiness is the same.Sometimes I cannot feel any emotion.My body becomes like a machine reacting and acting towards external stimuli.Does that say I am in a better state than before?

Lust

Lust is the most common emotion I guess we all feel.I mean till the day you are going to die... you have lust of differnt intensities.Lust has always been seen as something very negative and the society tries to paint bad pictures about the most evident emotion we feel.When you are attracted to a person it should be clear on what basis the foundation of your felling is based.Physically we are attracted to a person and we may dream of having a pleasurable relation.Mentally we get attracted,Spiritually we get attracted , all these things are the same thing.How can we rate and say that the physical is the least,then comes mental attraction and then spiritual attarction.
Most of the time the physical attarction fades away..so does the other mental and spiritual attarction.The problem is not with the other person ...the problem is with our minds.We always want some pleasure ...we hunt for pleasure...in every way ..in every person...in every opppurtunity...
If you lust for a person ...please go ahead and say it loud..that you do..you are human ...and thats why you feel it!!!
