color, scent, space, any tips will do
fengshui is not about color, not about scent, space - depends; it is not a decorating style.
fengshui is about a group of methods which are formulated for people to use nature to make life easier. but there is a catch, people cannot create good luck with the use of things, but we need to use these methods to adapt to nature.
first, you need to understand that there is NO book NOR website that offers to teach the both basic and advanced uses of these fengshui methods.
next to start, you need to understand that in fengshui, a house or a building (as in the case of a condominium) is always considered as 1 unit, thus, the most important part is the main front door of this unit - even if you just live in 1 bedroom in that house, or 1 condo unit in the whole building. the importance of this main front door is in its tilt, facing degree - the degree that is perpendicular to the outside (of the house) to where your main door faces. this must be measured accurately to half a degree. then you need to cross reference this degree with other configurations like void lines (which can cause a life of crime/ miserable/ dead end life), peach blossom (bad for home, but good for business; this can lead to many affairs, thus it is good for business - which can mean many clients in a business), etc. then if the degree is not ideal to you, then you might want to renovate your front door.
next is plotting the flying star chart for your house. here, the chart will tell you what spaces in your house has what kind of energy - the kind of energy is not generalized as to good or bad, but it is specific. so you know how to use an area, or how to build your house. people who practice fengshui use this to guide them designing their houses. the trick here is to live in the areas where there is good energy, while leaving the areas with bad energy as storage rooms, toilets, garage, etc. - rooms less used.
in fengshui, life always has an explanation; there is no such thing as cause and effect, because if you think this, then it is an endless debate. in fengshui, the cause is the energy in the house and your life/ energy. the effect is your life, what you are experiencing. so to change your life, you need to change the energy in the house. and the only way to do that is to know how fengshui works.
flying stars is not the only method out there. there are many. but what you learn in books are mostly what fengshui masters do not teach you in their seminars, because they just do not work.
if you are interested to learn the fengshui methods through books, get books by joey yap, peter leung, yap cheng hai, eva wong. i have taken some courses from yap cheng hai/ joey yap before. their courses are have more than their books.
