A spell is a formula of spiritual workings, it can very well be considered an expression outward in a systematic and respectful manner. With consideration towards a higher state, whether that be a guiding spirit, an angelic being, a spirit animal or simply to the essence of a flower, to wish it grow well and flourish in the bountiful sun.
It is our way as humans, to ask for the energy and assistance in guiding our wishes or intent into reality. But for us to fully appreciate the nature of this system you live in, and be able to coincide efficiently, we must take the proper steps to mature our sense of awareness. That way, consolation with a higher spirit becomes much easier.
1) If the proper steps are taken and respected it will take less out of your life force or chi in the give back process. You won't feel drained or in the negative after your spiritual excursion as your faith in consort will guide you down the correct path to reach your goal, or, they will be there to stop you if you lack concentration and lose focus.
2) You will be under the protection of a higher state, now this is very important, if you put out negative energy, specifically towards another person even nature herself will frown in your direction. You will always receive what you put out, and in my firm belief from many years of research it will always come back seven fold however you look at it. Be wary when dealing with entity. Especially if you do not have a clear conscience and most importantly a sound heart. This is how one may attract unwanted company. It is highly recommended that you meditate first to prevent any negative experiences.
3) I cannot stress this enough, and I apologize for caps but in this case I feel it necessary to get the point across. WORDS HAVE POWER... know that and think before you speak. It often helps to practice keywords that give out a good vibe, love, peace, harmony, grace, respect, are some of the best things you can comprehend in this life.
4) Don't ever skip steps, all things have thier natural order, and in that order are a set amount of rules such as, know the name of the entity you are being guided by, do not stray from your path for a moment and botch a spell because something was whispering nonsense in your ear (this goes back to sound body and sound mind). Know the names of those that bring you good fortune and happiness, and only call upon them when you are in need. Do not disturb them otherwise, they like thier rest as well, or more often than not they are very busy. Simply put, have manners and you will be well received.
5) I am fully aware that each person has thier own path to choose and they are entitled to thier opinions, but I would fully avoid trying to conjure or channel another spirit, the body is thy temple, do not taint yourself this way. There is a reason for the veil, and I strictly try to adhere to its set of rules. Keep a good moral compass and nothing shall steer you in the wrong path for you will have protection and safe travels.
6) Just be yourself, don't try to change things that you may otherwise learn a lesson from, sometimes it seems hard to understand at that given moment, but if you take a deep breath, and step back from the situation may you find clarity there in. Pay mind to this and you will prosper significantly from it.
