Many of us are familiar with Incense Sticks, I have just recently started to use resins, and the joy of using resins is really wonderful, I do not only use resins, I also add some sage to my burner and let it take all the negativity from my place. Yesterday I burned it twice and take it to my bedroom and let it stay for a bit, and honestly I had one of my best sleeps. 

The main reason to clear a space—your home, your car or your office—is to remove negative energies. Negative energies occur for a number of reasons. They include:

Metaphysical

Negative thoughts from current or previous owners or occupants

Disturbed emotional energy of current or previous owners or occupants

Disturbed environmental energy

Dimensional beings
