If you want to stop taking mutton, fish, etc., just see with your own eyes the pitiable, struggling condition of the animals at the time of killing. Now mercy and sympathy will arise in your heart. You will determine to give up flesh-eating. If you fail in this attempt, just change your environment and live in a vegetarian hotel where you cannot get mutton and fish, and move in that society where there is only vegetable diet. Always think of the evils of flesh-eating and the benefits of a vegetarian diet. If this also cannot give you sufficient strength to stop this habit, go to the slaughter- house and the butcher's shop and personally see the disgusting, rotten muscles, intestines, kidneys and other nasty parts of the animals which emits bad smell. This will induce Vairagya (dispassion) in you and a strong disgust and hatred for meat-eating. (Click here if you feel you need to see scenes from a slaughter-house to induce dispassion for meat. If you can't stomach pictures, you can read about one person's visit to a slaughter-house.)
All slaughter-houses should be abolished, and the use of animal flesh as food should be absolutely given up. Flesh-eating is unnecessary, unnatural, and unwholesome. The countless instances of reputed philosophers, authors, scholars, athletes, saints, Yogins, Rishis who lived on vegetable diet conclusively prove that vegetarian diet produces supreme powers both of mind and body, and is highly conducive for divine contemplation and practice of Yoga.
Man is created a frugivorous or fruit-eating creature. This scientific fact is evident on a comparison with the carnivorous animals from whom he differs completely in respect of his internal organs, teeth, and external appearances, whereas, anatomically, he is most intimately allied to the anthropoid apes whose diet consists of fruits, cereals, and nuts.
When man abandons flesh foods and takes his nutrient direct from nature's hand, of well-ripe and healthy fruits and grains, nuts and vegetables with addition of honey, cheese and milk, we shall find a large number of diseases disappearing. People will have more power of endurance and attain longevity.
What is needed is a well-balanced diet, not a rich diet. A rich diet produces diseases of the liver, kidneys, and pancreas. A well-balanced diet helps a man to grow, to turn out more work, increases his body-weight, and keeps up efficiency, stamina, and a high standard of vim and vigour.
People who are slaves to the flesh-eating habit cannot give up animal diet, because they have become confirmed and inveterate meat-eaters, and hence they try to justify their habit by various arguments and statistics. One cannot change their ways merely by argumentation and disputation. Ultimately, it is only the force of personal example that has a strong effect upon the people around you.
