Hi, I am Mr. Utpal Sikdar, born on 25th October 1970. I am a new learner of Feng Shui and this site helped me a lot in my learning curve. My element is Wood, Animal sign Dog and Kua no. is 3. I have toilet in the South-East corner of my house. As a pyramid's shape represents the fire element and fire and wood do not come in destructive sequence, can I put a Crystal Pyramid in the south-east corner oh my house? If yes, should the pyramid be placed within 3 to 7 feet height from the ground? Looking forward for your noble suggestion. Thanking you in advance.
