**Feng Shui** (風水（ふうすい）, *Fūsui*?, lit. "Wind-Water") is a Chinese system of beliefs and principles that is aiming to create harmony with one's surroundings through the proper arrangement of objects and the siting and construction of establishments.

In *Toaru Majutsu no Index*, Tsuchimikado Motoharu, is the only currently known practitioner of Feng Shui, and is referred to as an expert in it, as part of being an Onmyoudou specialist.

## Principles

Feng Shui is a magic system that focuses on the arrangement of things in a certain location to create a magic circle for a spell that activates the moment the circle is created, and its composition is dependent of its contents. The spell makes use of the energy (ch'i) of the world instead of the spellcaster's mana, as such, any person can create a spell using the principles of Feng Shui.

An apt analogy for this would be is that the power of the world is a generator, the spellcaster is a transformer, and the magic circle is the circuitry, which is switched on the moment the magic circle is created.

Feng Shui is explained by Idol Theory, as it still subscribes to the four elements, most specifically, its usage of the various colors, elements, cardinal directions, stars, and guardian deities, to find harmony with the world with the constructed magic circle.

An aspect of Feng Shui is the manipulation of surroundings in order to achieve an effect. Applied to terrain, this can be used to alter the ley lines. Good and bad land, as far as Feng Shui is concerned, can be discerned based on where mountains are, the directions in which rivers flow etc. By destroying and rebuilding the terrain, ley lines can be created and moved. Even outside of magic, filling in rivers and destroying mountains are not rare occurrences in modern times, and magicians using the earth have to work to make sure important magical points are not destroyed in this way.

## Background

According to Tsuchimikado Motoharu, Feng Shui originated in China, and there were originally no one who was specifically an expert of Feng Shui, as such, the Taoist priest would handle the aspects of arranging objects and other things, to find harmony with nature, this task is intended for the Onmyouji in Japan.
