I don’t recall Sri Ramakrishna tnaikg a stance on it one way or another, but then the Gospel is a very long book. Someone on another forum quoted Swami Vivekananda thusly. I have not verified these quotes. About vegetarian diet I have to say this first, my Master was a vegetarian; but if he was given meat offered to the Goddess, he used to hold it up to his head. The tnaikg of life is undoubtedly sinful; but so long as vegetable food is not made suitable to the human system through progress in chemistry, there is no other alternative but meat-eating. So long as man shall have to live a Rajasika (active) life under circumstances like the present, there is no other way except through meat-eating. It is true that the Emperor Asoka saved the lives of millions of animals, by the threat of the sword; but is not the slavery of a thousand years more dreadful than that? Taking the life of a few goats as against the inability to protect the honour of one’s own wife and daughter, and to save the morsels for one’s children from robbing hands which of these is more sinful? Rather let those belonging to the upper ten, who do not earn their livelihood by manual labour, not take meat; but the forcing of vegetarianism upon those who have to earn their bread by labouring day and night is one of the causes of the loss of our national freedom.(Complete Works, 4.486-7)All liking for fish and meat disappears when pure Sattva is highly developed, and these are the signs of its manifestation in a soul: sacrifice of everything for others, perfect non-attachment to lust and wealth, want of pride and egotism. The desire for animal food goes when these things are seen in a man. And where such indications are absent, and yet you find men siding with the non killing party, know it for a certainty that here there is either hypocrisy or a show of religion.Complete works, 5.403)
