Anyone can have a small altar at home, where we see two images, one of Sri Krsna, the other the spiritual master. The easiest way to offer our food is placing food in front of these pictures and say, "O Krsna, dear Lord, please accept this humble offering" and chant Hare Krsna. Sincere devotion is what counts in this offering. God is not hungry for food, but our love, and when we eat these purified foods that are accepted by Krsna, we free ourselves of our karma and we become immune against any material contamination.
4. The positive principle of offering vegetarian food to Krsna naturally implies prohibition of eating meat, fish, or eggs. Eating meat is participating in the unnecessary killing of other living beings. This raises bad reactions in terms of karma in this life or the next life. The laws of karma explain that whoever kills an animal for food will himself become a victim in his next life and will in turn be eaten. There are also some karma to take the life of plants, but it is canceled by the process of offering food to Krsna, because the Lord said that he accepted such vegetarian offerings. It must also renounce the exciting and toxic substances, including coffee, tea, alcohol and tobacco. Intoxication of the sort returns to be influenced by ignorance, and could lead us to a lower birth in our next life.
5. Other techniques to free themselves from the cycle of reincarnation include the offering to God the fruit of our labor. All men have to work to provide for their bodies; but if one acts only for his own satisfaction, he must then accept the consequences caused by karma - whether good or bad - at future lives. The Bhagavad-gita says that action must be to the satisfaction of the Lord. This action takes devotional service name, and it is free from karma. Act in Krsna consciousness returns to make sacrifices. Man must sacrifice his time and money to the satisfaction of the Supreme Being. "It should provide the action in sacrifice to Visnu, lest it connects its author the material world." (Bg , 3.9). The action performed as devotional service not only protects the person of karma reactions; it gradually rises transcendental loving service of the Lord - that is the key to access the kingdom of God.
It is not necessary to change activities. A writer can write for Krsna, an artist paint to Krsna, a cook do business for Krsna. For those who can not directly use their talents and abilities for Krsna service, they can sacrifice the fruits of their labor by giving a portion of their salary to help spread Krsna consciousness throughout the world . However, always make a living by honest means. For example, it should not be a butcher or live the game.
