Fruit trees should be in the East because the sweet rays of sunrise fill the fruits; even the mouth feels sweet before sunrise. To create sweetness in relationships, in society or in the family, the East is selected for such work.
The magnetic anomaly of the East is directly connected to the West and balances it; the devta Aryama draws the full energy of the sun and passes it on to Mitra. Of all 16 zones, gravitational force is most balanced along the East-West axis through the centre (Brahmasthan). The rays carry gold content, which is why Aryama is shown in gold. Gold binds people, as a gift of gold keeps a relationship for life, so the East is called the social contact zone. It is also very good for meditation and study.
