I have successfully experimented the android app kamea sigil. I put in formula "extremely thick mist throughout Toronto city in canada Namo Sado Nah Samyak Sampo Doh Jee-tzu Nah Dah Zah Tou Ohm Zhurli Zhuli Zhunti Soha Ohm Brin or nam myoho renge kyo". You can use either or both mantras. The first one is zhunti mantra(pronounced as chuntee) and the second one is a budda mantra.
I use the mantras to empower what I want. Do NOT use the kamea sigil app with either mantra on yourself or others because you may feel a lot of pressure in the head or feel very tired to the point of painless death(you may not die, but anything is possible).
I am not responsible for what you do with this knowledge. Experiment at your own risk!
I did as above mentioned mist mantra sigil. The date I did it is Monday, September 10, 2018 in the city of Toronto in Canada. You can check it out on the www.theweathernetwork.com for Canada, Ontario, Toronto
No, it is kind of a new kamea, the kamea app uses 7 angels, 7 archangels, and 7 planets producing the strongest kamea possible. Now the classic kamea makes the mantra very ill deathlike. The kamea app is more gentle and eases you to sleep long, more like a gentle sleep. I used it on myself.
