Magic can be used for many things, protection, health, love, power, and more. The basic thing you should keep in mind is that for magic to work, your goal must be logical. Spells that supposedly turn you into a vampire, werewolf, or any other creature that isn't a human, will never work. That goes for spells that make you control the elements, allow you to fly, or any other nonsense like that. There are many things in this site that will help distinguish the real stuff from the fake, apart from your common sense. I hope I was able to help.
Magic cannot break any law of physics.The idea is to change what can be changed; emotions,feelings,environment,attitudes. It cannot go against Nature, but can use Nature, at least a little,to change your immediate environment.
Strictly speaking, magic is knowledge, and we never stop learning.
Magic is not waving a wand about like Harry Potter!
Some uses of magic can be easy;but serious magic can take a lifetime to learn.
So,study nature. How the Earth works, how the Universe works.
It is a lot of reading; a lot of study.
We are "seekers of knowledge and enlightenment".
The journey is a long one; but full of the joy of living.
Good luck in your search.Don't be in a hurry. Learn how to meditate, and then everything else will fall into place.
Blessings from an old witch.
