Well You might start by researching the ?abilities? and where they come, Yourself.
Learn about human bodies, not just the physical one , and learn how the energy runs through them. Learn what and where are energy points, from basic 7 chakra, to acupuncture spots and energy meridians If needed. Learn how much and in what manner does psychological profile affects what "abillite s" will someone be most proficient in/at using.
Learn about centering, grounding and energy channeling. Then start with exercises, depending on type of "abilities" You are interested in , PSI or ESP
For example, a good exercise for remote seeing is observing some relatively distant scenery for about five minutes, doing Your best to memorize all the details. Then one closes eyes and tries to visualiz e what they saw in all the ( possible ) glory od details, and the when they open the eyes they check how correct were they in their visualization.
You can randomly cover a hand- watch with Your palm and try to guess the exact time, this is a simple exercise for developing precognitive, and remote seeing abilities.
Throwing the dices while focusing on numbers 1-6 and trying to influence e the way they fall is considered to be a fine, beginner telekinetic ability exercise and test .
There are rituals, charms and spell s, used to help one reach their full spiritual potential, and increae their spiritual ?abilities? . You can look up "King Solomon wisdom oil" , "African Ju Ju oil", "Master key oi l" or other kind of magickal product of same brand ( incenses, bath salts , powders and so on ) , and how to use them.
Amulets and crystals can help as well, when properly chosen and used . For example Ulexite, and double terminated crystal increase one's telepathic talent s , and are amazing tools for sending mental messages. Cherry opal is one of the par excellence precognition stones. Sigil Dei Ameth, fist used by Dr Dee is a ritual symbol l that shall lend a lot of power to any scrying ritual and so on
