Feel free to post your own techniques and also experiences;)
Fire and Water Meditation (This meditation will allow you to stay warm during cold and purify yourself using your breath) I will post more on how to enter a trance state and call upon your spirit guides and angels to help you activate the healing energy inside. After that we will talk about healing different aspects of the body and how to detect illness.
Here is the meditation:
Close your eyes and take a few deep breaths, let yourself become relaxed in your chair. Imagine your breath as a halo and surrounding your body with fire. Feel this fire warm you, take it into your physical body as you inhale and imagine it coursing through your body through your veins giving you warmth. With each exhale, imagine the fire leaving and connecting a strand with the divine to your heart chakra. You can use the affirmation: "I am protected by the divine. No longer am i cold."
To purify yourself, possibly a part of your body (It can be a part of your body that you are criticizing about or have some trouble, pain there):
Imagine your breath as fire surrounding the area giving warmth and healing to the area. Next exhale and connect the fire to the divine again. Then imagine you are standing in a pool and there is a waterfall. Go near the waterfall and imagine the water cascading down throughout your body washing away negativity. Protect yourself from negativity by imagining your breath as a white light forming a halo protecting your aura and affirm "I am at peace. I am protected and healed from negative energies."
(You can use two different colored beads on a string to measure the balance of your in-breath and outbreath. Spend time in the meditation for 10-15 minutes and practice it for at least 3 weeks or as long as you need to.)
