Why do an underground water tank, drawing room, puja room and conference room suit Shikhi (E1)?
When Adi Prabhu (Shiva) did sadhana on Kailash, the friction produced heat that began to melt the mountain, so water matters most for cooling this place; Shikhi's energy stored with water also spreads through the house and keeps removing about 50% of its vastu doshas. In the drawing room the family sits as if in sadhana and makes its plans and policies, and in a conference room others are convinced with one's ideas and vision and given targets. Worship of Adi Prabhu (Shiva) in a puja room here raises the energy further; an office and a borewell also suit this pad.

Does the coconut kalash for Parjanya work when kept outside a door at E2?
Yes. In a flat seen on a recent visit, whose door is exactly at E2 (Parjanya), the resident keeps a water-filled kalash with a coconut on it outside the door and changes the water daily; the coconut has grown into a large plant, and the resident reported very good results for ten years without needing any planetary remedies. This is exactly the remedy prescribed for Parjanya.
In the vastu purush concept, should the NE diagonal be kept free of an underground water tank?
Correct, not on the exact diagonal where the head of Shikhi devta falls. Vedic vastu calculates the Shishu Pishach points, and no shilanyas pit, water pit or any other pit is dug on them; this is taught in the diploma.
Why is a doctor's chamber the best use of Parjanya (E2)?
No doctor is bigger than Parjanya: it is the doctor of crops, of humans and of animals, giving them productivity and the power of generation. So a doctor's chamber is the most important orientation at E2, and a conference room also suits it.
A wooden temple with elephant figures stands in the North-East. Is that fine?
Elephant figures should stand on something solid, not hang in the air. The temple can stay, but a temple with elephants is better placed in the West.
Can a bedroom be made at Shikhi (E1), and why should it be white rather than red?
Yes, a bedroom at Shikhi can suit elderly people, and it should be painted white rather than the zone's red colour, as advised for people of kapha nature and for those of pitta nature whose heat rises quickly. Shikhi is highly sensitive and already hot, so red would add heat and open the third eye.
Do these boring and underground tank rules apply to farms too?
Yes, the same rules apply to farm land.
