One must execute devotional service under the guidance of a devotee or directly under the guidance of the Supreme Personality of Godhead. It is not possible, however, to train oneself without guidance from the spiritual master.

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.

When a pure devotee or spiritual master speak, what he says should be accepted as having been directly spoken by the Supreme Personality of Godhead in the Parampara System.

It is imperative that one approaches a spiritual master, for by such association one proportionately develops his consciousness towards the Supreme Personality of Godhead.

In spiritual life, one must conduct one's whole life under the guidance of the guru. Only one who executes his spiritual life under the direction of the spiritual master can achieve the mercy of Krishna.
