You can use a laser crystal to energize your entire aura. This can help seal up any holes in the aura.
Take a clean, and consecrated crystal, you can learn how to do that in Master Choa Kok Sui's book Pranic Crystal Healing.
Hold the crystal in the palm of your non dominant hand, with the tip pointed towards your wrist, and program the crystal to energize your body with green energy for 1 minute.
This will flush the chakras and aura of dirty energy.
