Take a system like your body/mind/spirit/connections.
If you have areas of tension or conflict, these tensions and conflicts will increase when you increase your energy level.
This is why all religions and spiritual systems have some form of purification ritual in their practices.
You purify yourself physically but as well internally so that your channels are clear.
If you are angry when you try to increase your energy level, you increase as well the level of internal tension which can lead to more conflicts and even self destruction.
This is why you need to be very smart when you engage in any form of spiritual practice.
You need to solve what is unsolved.
You need to increase your level of love, respect and harmony, while gaining power at the same time.
Now, the way you use your power is essential as well.
