One who loves Krishna will give Him whatever He wants, and he avoids offering anything which is undesirable or unasked for. Thus, meat, fish and eggs should not be offered to Krishna...Vegetables, grains, fruits, milk and water are the proper foods for human beings and are prescribed by Lord Krishna Himself. Whatever else you eat, can not be offered to Him, since He will not accept it.
Spiritual master is representative of God. Similarly, king is also representative of God. The father is also representative of God. These are the statements of the sastras. Because they will guide. The king will guide. The spiritual master will guide. The father will guide. What is that guidance? That guidance is how one can become Krishna Conscious by education, by culture.
To be nonviolent to human beings and to be a killer or enemy of the poor animals is Satan's philosophy. In this age there is always enmity against poor animals, and therefore the poor creatures are always anxious. The reaction of the poor animals is being forced on human society, and therefore there is always strain of cold or hot war between men, individually, collectively or nationally.
First birth is from your parents, but real birth, real life, begins when one accepts a bona fide spiritual master and renders service unto him. Then the path is open for going back to home, back to Godhead, to live eternally in full knowledge and full bliss and in association with the Supreme Personality of Godhead Himself, Lord Krishna.
Our first duty is to satisfy the spiritual master, who can arrange for the Lord's mercy. A common man must first begin to serve the spiritual master or the devotee. Then, through the mercy of the devotee, the Lord will be satisfied. Unless one receives the dust of a devotee's lotus feet on one's head, there is no possibility of advancement. Unless one approaches a pure devotee, he cannot understand the Supreme Personality of Godhead.
When a Krishna Conscious person is elevated to a responsible position, he never becomes puffed up. Just like a tree when over-laden with fruits becomes humble and lower down. Similarly, a great soul in Krishna Consciousness becomes humbler than the grass and bowed down like the fruitful trees because a Krishna Conscious person acts as the agent of Krishna, therefore he discharges his duty with great responsibility.
The artist draws a picture of a rose very nicely with all attention and artistic sense, and yet it does not become as perfect as the real rose. If that is the real fact, how can we say that the real rose has taken its shape without Intelligence behind the beauty?
Out of many millions of wandering living entities, one who is very fortunate gets an opportunity to associate with a bonafide spiritual master by the grace of Krishna. By the mercy of both Krishna and the spiritual masters, such a person receives the seed of the creeper of devotional service.
Therefore a person fully absorbed in the bodily concept of life is surely killing himself by not making spiritual progress. Such a person is called pasu-ghna. Especially excluded from spiritual life are the animal hunters, who are not interested in hearing and chanting the holy name of the Lord. Such hunters are always unhappy, both in this life and in the next. It is therefore said that a hunter should neither die nor live because for such persons both living and dying are troublesome.
It is said about Lord Buddha sadaya-hrdaya darsita-pasu-ghatam. He saw the whole human race going to hell by this animal killing. So he appeared to teach ahimsa, nonviolence, being compassionate on the animals and human beings. In the Christian religion also, it is clearly stated, 'Thou shall not kill'. So everywhere animal killing is restricted. In no religion the unnecessary killing of animals is allowed. But nobody is caring. The killing process is increasing, and so are the reactions. Every ten years you will find a war. These are the reactions.
The spiritual master and Krishna are two parallel lines. The train, on two tracks, moves forward. The spiritual Master and Krishna are like these two tracks. They must be served simultaneously. Krishna helps one to find bona fide Spiritual Master and bona fide Spiritual Master helps one to understand Krishna. If one does not get bona fide Spiritual Master, then how he can ever understand Krishna ? You cannot serve Krishna without Spiritual Master, or serve just Spiritual Master without serving Krishna. They must be served simultaneously.
