Train each sense individually first, once you can experience one easily, move on to the next. When you have the 5 normal senses all down, start merging them, first 2 at a time, then 3 etc.
Two quick tips. Being in the trance state will speed this up. It is better to start in trance then start the practice, than to eventually get into trance via the practice. Secondly, when it comes to sight, you will normally have an easier time visualizing something moving rather than it being static. A ball bouncing, or a flower in a gentle breeze are much easier to see internally than either of the same as an unmoving thing.
It's important that you don t overlap before ready. not because of danger, but because it can slow you down. for example, smell a scent that is both potent, and familiar to you. let's say it is a spice. you want to smell the spice, without seeing or tasting it etc.
This will give you a basic gauge of where your internal senses are ranked against each other. when you can merge all 5 into a stable visualization, the step after that is to do the same with your eyes open. the same training is done but now eyes open. eventually you will develop hyperphantasia, and be able to experience synestia at will.
Magic becomes much more real at this point in training. and you will notice the effects of your spells/etc take place significantly faster. Even just 20 minutes a day will do wonders if you do this consistently. More time is always better, but quality and quantity have to be balanced.
