You have learnt about different type of fasting, now take a look at why fasting is necessary?

Why Fasting Is Necessary?

The history of the practice of fasting does not have a specific beginning date; it has existed for a very long time. The scriptures go into great length about the commandments of fasting and breaking. Fast observation allows for the removal of both physical and mental illnesses. Fasting has been a ritual since yesterday. Fasting has long been used for mental clarity or to fulfil any purpose. Mahatma Buddha fasted in order to reach God.

In legendary times, Lord Rama fasted before the ocean to make space for his army of monkeys. To get married to Shiva, Goddess Parvati had fasted.

Fasting is highly beneficial for treating bodily problems. Everyone is aware that all illnesses originate in the stomach. All of our illnesses may be cured by managing the mind and the stomach. Our belief in fasting grows much stronger if we consider the animals. When sick, all animals—including cows, dogs, and birds—stop eating. And eventually, they recover.

The flavour in our tongue leads to sickness in a similar way. We desire to consume less food. We don’t feel like eating right now. But medical professionals advise eating. We believe that through eating, our bodies will get stronger and the patient won’t deteriorate. The severity of the sickness increases with the amount of food consumed when unwell.

Scientifically speaking, fasting is a way of sickness therapy. Fasting is the practice of consuming just water and no solid foods. The simplest method to avoid the negative effects of overeating is too fast. The components in the body that cause sickness are expelled during a fast. The body needs rest the most. The body is given relaxation while you fast. The strength needed for movement is provided to the bodily components. The body’s components get stronger so they can do more job. The heart is refreshed. Makes the heart robust and healthy. Heart conditions are eliminated.

The state of the tongue and respiration both alter when fasting. The tongue reveals the state of the patient. The colour of our tongue changes as our appetite grows and the moment for breaking the fast draws near. The tongue gets pink in hue. In the breath, a distinct sort of smell is released.

Fasting is said to cause pain. This is true, but the faster we think about how unpleasant fasting would be, the less painful it actually is. Only the first two to three days of a fast are uncomfortable. The food that we are currently craving is just a result of our hunger. There is no discomfort experienced by the patient.

Long-term fasting causes a patient to experience various odd symptoms. With these symptoms, there’s no reason to get alarmed. It is important to remain patient. The symptoms of the condition manifest during fasting if the patient has ever had it and been treated for it with medication.

How Do You Begin Fasting?

You ought to limit your food intake for the first one or two days. Following this, a fruit-only diet should be followed. Only juice should be drank after consuming solid fruits, followed by a full fast. Fasting should involve more rest. Spending these hours of relaxation outside or in the sun is recommended.

The fasting guy need to have entire trust in his fast. It is recommended to read a book on the fast before beginning it.
