Eating animals for taste makes your heart and mind dull and less kind, so it’s harder to grow spiritually.
From the Discourses
Passages where Osho speaks to this question — each links to the complete discourse.
Osho, the Gita certainly emphasizes sattvic food for seekers, but nowhere does it explicitly forbid meat. And you have said meat is easy to digest—and that’s what doctors say, too. Then what obstacle does meat-eating create? For spiritual practice you have strongly stressed the usefulness of a vegetarian diet. But books indicate that many saints who attained through Sufi, Zen, and Tantra paths did not remain vegetarian. And in our own country, Paramhansa Ramakrishna always ate non-vegetarian food. What is the reason for this contradiction?
Then my vision is this: Ramakrishna is an exceedingly pure man. Therefore such a small impurity could not obstruct him. You may not be able to conceive this. Exceedingly pure. If you permit me, I would say: purer than Mahavira. Had Mahavira eaten meat or fish, he could not have attained the supreme. But Ramakrishna did. This means only this: the man is so pure that such a small impurity could not hinder him. Despite that impurity he crossed beyond. Understand it like this: you climb a mountain. The rule for mountain-climbing is that the less the load, the better. If you climb with loads of weight on your head, climbing becomes hard. You may abandon the idea or stop at some midway camp. But then a very powerful man, a Hercules, climbs the mountain with a heavy weight—and reaches the top. This man is not the rule. This Hercules…
If Mahavira also preferred vegetarian food — not meat — it was not only for ahimsa. Ahimsa was one reason. But more important was this: meat demands more power to digest; it makes the body heavier; it makes the stomach more important; it depletes the brain’s energy and deepens stupor. If ahimsa alone were the reason, Mahavira could have said: there is no harm in eating the flesh of animals who have died naturally — Buddha even allowed this. If only nonviolence were the cause, then do not kill; the violence lies in killing, not in eating. An animal has died — we did not kill; we eat — where is violence? In eating the flesh of the dead there is no violence. Buddha permitted it. But Mahavira did not permit even that. Because his purpose was not only ahimsa.
It is also asked: Muhammad ate meat, Christ ate meat, and yet they attained samadhi!
You have seen: herbivorous animals eat all day long; the carnivorous lion eats once in twenty-four hours. Why? Meat is so heavy it takes twenty-four hours to digest. The monkey sits in the tree—he’s vegetarian—and keeps nibbling whatever he finds. Why? Vegetarian food is light; it doesn’t land like a stone. And whenever the body is heavy, it is difficult to fly into the sky. Whenever the body is heavy, touching the heights of meditation is difficult—not impossible, but difficult. Haven’t you noticed? When you eat a lot, sleep comes. Understand a little from that. Why sleep after heavy food? Because staying awake becomes difficult. The body is so heavy it wants to sleep. After a heavy meal you won’t be able to sit for meditation; if you try, you’ll doze, sleep will come. That is why people discovered fasting. Meditation on a light or empty stomach can settle in…
43. Austerities destroy impurities, and with the ensuing perfection in the body and sense organs, physical and mental powers awaken.
44. UNION WITH THE DIVINE HAPPENS THROUGH SELF STUDY. 45. TOTAL ILLUMINATION CAN BE ACCOMPLISHED BY SURRENDERING TO GOD. These are all austerities: fasting; natural eating; deep, rhythmic breathing; yoga exercises; living a more and more natural, flexible, supple life; creating less and less suppressed attitudes; allowing the body to have its own say, following the wisdom of the body. "Austerities destroy impurities...." These I call austerities. "Austerities" does not mean to torture the body. It means to create a living fire in the body so that the body is cleansed. As if you have thrown gold into the fire -- all that was not gold is burned. Only pure gold comes out. <q>"Austerities destroy impurities, AND WITH THE ENSUING PERFECTION IN THE BODY AND SENSE ORGANS, PHYSICAL AND MENTAL POWERS AWAKEN."</q> When the body is pure, you will see tremendous new energies arising, new dimensions opening before you, new…
Beloved Osho, when you were testing your enlightenment by smoking, drinking alcohol, and having sex, did you try eating fish and meat? Does a vegetarian diet have a real value for our consciousness, or is it optional, like smoking?
Of course, there is some existential difference which I cannot destroy. But this is not the existential difference -- that you smoke and I don't smoke, that you drink and I don't drink. This is not existential. The existential difference is very small, and that is: I am awake and you are asleep. It is not much, because I am just sitting on the same bed where you are asleep. Just a little effort will make you awake. Your sleep gives a guarantee: anybody who is capable of sleeping is capable of awakening, they come together. So what is the fuss about? Take your time. Whenever you want to wake up, wake. There is no hurry, you have the whole eternity available to you. Yes, I may not be there to wake you up, that is the only unfortunate thing about it. But somebody else.... One day you are going…
