There really is no "must", but certain procedures such as spiritual warfare help individual to better their situation. Oftentimes considerably, especially when timing and consistency are followed through. To not follow through with the above is a great disservice to yourself, and indirectly to others as these help us collectively as well. Practically, it is more about what propels you and us forward, and what does not. Logically, moving forward with a positive trajectory is always preferable to something else.
If you feel overwhelmed by the energy you raise you can opt for a lesser amount of vibrations for the time being. In Gods' rituals the smallest amount is 5 repetitons per Rune.
And if this is too much you should focus on other aspects of development that will eventually bring you to a point where you can handle more energy.
Being more stable in general sense is one of the properties of the earth element. If your soul has very little elemental earth you can have trouble handling the energy you raise. To balance this issue you can work on that issue specifically. There are multiple methods, such as Sanskrit planetary mantras, runes, elemental energy and so on.
