Presence is extremely important in the law of attraction. Presence is the quickest way to get to a place of detachment and letting go. When you practice being in the present moment, you drop all of your worries, your concerns, your needs, your wants, and your attachments. All of these things are in the future and the past. When you are present, you just exist, and you open yourself up to receive.
To be present is to LET GO. Letting go is required to attract what you desire.
