Pure desire: is authentic and you are worthy of all good things.Your mind and emotions are working as a team.In your mind's eye, you are envisioning abundance and are looking forward to watching the overflowing of riches manifest. You are at a place of no doubt!
Longing: is a desperate yearning, wanting.A despair that if you don't have such and such, you feel like you are not going to survive.You are full of doubt and unworthiness,your mind and emotions are not on the same team.
Hinduism and Buddhism talk about being non-attached. However, being attached-leads to suffering.
Non-attachment is the authentic desire.Attachment says,we desire a certain result and fear the result will not be obtained.
Clearly attachment is full of doubt, and non-attachment exudes confidence.After years and years of trying to figure this wisdom out...
In my life, if I didn't care one way or the other that means I was detached- life flowed.However, when I yearned as opposed to a pure-desire, life didn't bring me my desired result because I was full of unworthiness and doubt.
So, detachment means- a sense of being alive with the mind and emotions working together, where one knows they are worthy and knows of no lack = the ultimate-this is the law of attraction!
