Generally its not a good idea to forget a spell once it's cast, when you forget the spell it can lose the focus behind it causing it to be less potent or causing undesired side effects that could have been avoided, like jumping into a bumper car and not steering, also many keep records of spells they have cast for a variety of reasons for example if they encounter a situation that the spell could help with, or help them improve the spell and make it more effective. However if I always recommend going with whatever works for you, though its good to experiment and find ways to improve (as long as you don't put yourself at risk), after all knowledge is power, this is especially true in magick
Yes. If you forget about a spell you cast, you allow the power to diminish. Plus you have no way to track the progress of the spell and know if it worked or not. If it didn't work or was not as effective as you wanted, you want to be able to go back and adjust it for future use.
In what ways has forgetting about a spell been effective for you? Maybe we are misunderstanding what you mean by this?
Because I'm not sure I know any pagan, or other magick user, ever willfully forgetting about a spell, and claiming for it to have made a huge difference for them in a positive manner. If You actually do mean it in this way, then I agree very strongly with Skywing and Bo; You need to remember the spells you've cast for a multitude of reasons, whether it be for the sake of learning and keeping track of your spells and progress, or because you need to continue sending energy to the cause, etc, memory is key to ensuring success.
May Be I can help a bit here Forget a spell do not mean that forget it completely but the fact behind it was that peoples dont say every day after a spell cast "When will my spell work Is it working or not etc" This all creates doubt in us that cause failuer of spells so its not really to forget a spell but to forget doubting on it by not to thinking of spell much like when how shall it work or is it working or not..But to remember you casted a spell and have faith on it and believe so if shall work fast ..Sorry If I am anyhow wrong ..
Blessed Be
In chaos magic after making and charging the sigil it is best to forget about the casting. The reasoning behind this is that thinking about casting could draw the energy you sent out back to you before it has time to manifest in the physical world. I have only heard this during my study of chaos magic but I havent heard this anywhere else.
