There are several major schools of Ikebana that have different styles. They all adhere to these 7 basic principles:
1. SilenceIkebana is a time to observe nature. To work with nature and find it's form. It's not a time for idle gossip.
Ikebana brings peace to your mind and makes you more tolerant.
2. MinimalismIkebana is influenced by Buddhist ideals of minimalism.
3. Shape and LineThere's an emphasis on shape in ikebana. As with everything else in ikebana, shapes should be minimal and natural. Lines are graceful.
4. FormThe form of a ikebana arrangement is found rather than planned. You find what is already there in yourself and nature.
5. HumanityIkebana incorporates humanity as well as nature. You can make ikebana a reflection of your feelings.
6. AestheticsIkebana has a distinct aesthetic that's difficult (or impossible) to describe in words. It's something you just have to feel.
7. StructureThe basic structure of Ikebana is a scalene triangle delineated by three main points. These are often formed with twigs. The three points of Ikebana represent heaven, earth and humanity.
