I meditated on candle flame since I was 5-6 years old. In the last years from my notes cumulated, I meditated on a candle flame for over a week in total—more than 150 hours. Usually, an hour a day from time to time, nothing wrong happened, but quite the opposite. More clarity and spiritual ability. I do not take into account the divination part of it, just pure focus and will in certain cases.
I also am of the opinion which is something of personal performance, that flame meditation is essential and also a gateway to developing a lot of not only abilities but also advance very powerfully.
Besides this, is pointed meditation on a .... point. All of this sounds for beginners but truly it is not, and it is a way to actualize a lot of power and acknowledge a lot of things.
If you really like this and get the feeling of it, you can hypnotize and command anyone to realist degrees. You can make things happen only by your gaze if you also have a powerful electromagnetic field.
You can also communicate with animals, to a certain degree as this also involves emotional intention. You can send images to animals. I befriended my parrots in this way, by showing them what will happen if they come to me. Also, cats and dogs are the easiest to communicate with. If you connect to them, you'll know when they'll be sick, when they are thinking of you, etc. If you get a pet you'll also know if they like you or not, as for example, some parrots chose their caretakers very carefully. If they don't like your face you'll know.
