1. You have no business going on a site if you do not believe in yourself. If you do not believe God will protect you, you have work to do. Always keep your faith that God will keep you well. Believe that God will protect you, and that you are worthy of that protection. Always know that you and only you have the power to keep yourself safe from any and all negativity.
2. Never go to a site angry or distraught. A personal negative attitude will only attract negativity to you, including negative spirits. Make sure you are in a positive frame of mind.
3. Never go to a site if you are too sick or tired to be there. In order to keep yourself safe from anything entering you that should not be allowed, it is important to be healthy, and not weakened mind, body, and soul.
4. Never go to a site drunk, or under the influence of any substance. Just as illness, anger, and sadness can lead to increased negative influences on you during an investigation, so can drugs and alcohol which can alter our state of being emotionally and physically, which leads to a weak spiritual body as well, leaving an opening for negative influence. It is important to always remain in balance and at our best.
5. Start with your own personal prayer before leaving for the investigation. The main idea of the prayer is to bring a feeling of strength into your mind, and to establish a sense of protection and connection with God. This should only take a minute, and could be as simple as the following:
Lord, please keep me pure of all negativity. Allow me to collect scientific data that proves whether or not this is a true haunting, and allows me to know what can be done in order to help those involved in this situation. Please allow me to do this without any harm coming to myself or others physically, spiritually, or emotionally. Amen.
6. A simple visualization can also be performed. Again, the idea is to mentally image what you intend to make happen, thus removing your own negativity, and preventing other negativity from entering your private space. A proper visualization for this could be as simple as the following:
Get yourself in a comfortable / meditative position and close your eyes. Imagine that a beautiful, bright, white light is glowing from your heart. With each beat of your heart, that white light gets bigger. It grows and grows until your entire being is covered. This process should help you to eliminate all negative energy from your body, because as the white light grows through your body, it pushes the negative energy outside of you. Now, extend your light out to create a circle around you about a foot outside of every part of your body. Seal your circle off like a bubble, protecting yourself from all outside negativity.
7. Once you are together with your paranormal investigative team or group, a group prayer and visualization never hurts, because there is always power in prayer and in numbers.
