Hello,
Here by the harmony of opposed force, chaos and order, those melodies will be sure a pleasure for you and for me, once since the very time, the foundation, we've seeking guidance no longer trough natural order only (Satan) but we tried to connect with our side that tends to be creative in exploiting the natural forces.
Why beliefs systems tends to protect people (IMHO), it might be because we don't see the whole reality, we believes to replace the need to understand everything, or it may create cohesion, acceptance, or even "yell" messages within the full spectrum of reality that can be decoded by invisible yet unknown forms of energy/entities. (Like when a baby cries to his mother, we can yell at the universe, and who knows, something may occurs).
Most people live in cities being jammer to the aura they broadcast, everyone can be polluted in the subconsciousness and attract bad luck without healthy routine or spiritual rituals. Reverse the trend.
I study esoteric meaning and occult book, I didn't had to break the rules to read about it, I am me and I am free, but the best rituals are by far within a ratio made of "Benefits / Risk of loss" which is chanting names of sacred entities, it can be the name of god, or other deities, this is what most magic rituals are made from. Giving something is as much powerful than being able to receive.
I can say that to me, they all seem to be clearly no bullshit, it's not as hard as matter within reality, but I feel like, it gives you that special intuition that can be a difference in a battle. It's so important to stay tuned to the universe.
NAGA MANTRA
This one is an old aged mythological mantra associated with wisdom, strength, and generosity. Some people call the Nagas the Patayanak (probably reptilians in modern myths)
SHANI MANTRA
This one is associated to Saturn a planet that influences positively patience and honor. Tho I've never been on Saturn, I suppose the diety/planet/influence can alter my reality and bring positives outcome.
ASHTAR MANTRA
This one is a new-age mythological mantra but I don't know what it is designed for doing. As long as worshiping a planet or deity can work, I don't see why it would be completely worthless.
