Right okay, so I want to cast a spell but do not have any special herbs or stones or anything like that.
Are the items necessary and do they mean something or can I make a spell myself because I heard some witches do that. Bear in mind I am very new and have never cast a spell before.
They are used more for helping to focus and better define your intent. Sometimes they are used to draw power from. Depending on what it is you are trying to do your intentions alone can often be enough.
I believe that spells you make yourself are the most powerful. As stated, if you have the will, drive, and intent, your spell should be alright without herbs and stones to assist you. They can be helpful, but they aren't necessary to spell casting. If it is unsuccessful, keep at it! Magick takes patience and practice. Best of luck to you :)
If you're serious about learning how to do magic and with starting from the rock-bottom then you don't start out by casting spells, you start out by learning how and why magic works.
You see, there is no such thing as an "easy" spell or a "beginner" spell. One either understands how magic works and has mastered the basics...in which case the magic will work..or you haven't done that sort of work..and no spell will work no matter how "easy" it seems.
Casting a successful spell involves much more than finding some spell on the internet or in a book, saying some words, lighting a candle, waving a wand of any of that sort of thing. In order for magic to work you need to understand how and why it works in the first place. Grounding and centering, visualization, focus and intent, energy manipulation, etc are all necessary first steps to even begin to have a chance at a spell actually working...and more importantly to prevent a spell from back-firing on you.
So, my advice for anyone who is truly serious is to start by reading a few books and practicing the exercises those books will give you. Once you have mastered the basics you won't need anyone to give you spells, you'll be able to create your own spells that will be far more effective than anything you find on the net. Here's the books I suggest:
"Before You Cast a Spell" by Carl McColman
"Spells and How They Work" by Janet and Stewart Farrar
"The Veil's Edge" by Willow Polson
"Modern Magick" by Donald Michael Kraig
And the following links in this thread will also help you learn the basic skills necessary for effective spellwork.
Any sort of materials, like crystals, herbs, candles etc, are nice to have (and I personally love using them) but it is not necessary. All you need to cast a spell is intent and focus.
