Kejawen knowledge is generally learned by chanting spells and performing certain rituals, such as fasting and meditation.
Fasting and meditation are two things that are very important in the process of spiritual enhancement. Almost all religious teachings recognize the ritual of fasting, although with different names and versions. If dug deeper, fasting does have a very good effect on the body and mind. By fasting a person can change the body's molecular system and increase its vibration so that it becomes more sensitive to supernatural energy and power. Even the ability of the sixth sense can also be raised by fasting, because all the negative energy in a person's body will be wasted on its own as fasting is carried out by that person. Once the body has been cleansed of negative energy, we will automatically become more sensitive to spiritual and supernatural symptoms or phenomena that occur around us.
