Balinese pekarangans are influenced by the philosophy of tri-hita-karana that divides spaces into parahyangan (top, head, pure), pawongan (middle, body, neutral), and palemahan (below, feet, impure). The parahyangan area of a Balinese pekarangan faces Mount Agung, which is regarded as a sacred place (prajan) to pray (sanggah). Plants with flowers and leaves that are regularly picked and used for Balinese Hinduism liturgical purposes are planted in the parahyangan area. The pawongan area is planted with regular flowers, fruits, and leaves. The palemahan area is planted with fruits, stems, leaves, and tubers. Balinese back yards, which are known in Tabanan and Karangasem as teba, are used as a place to cultivate crops and keep livestock for subsistence, commercial, and religious use as offerings. The Balinese further developed beliefs about what plants should and should not be planted in various parts of their pekarangans, following the teachings from the Taru Premana manuscript. As an example, nerium and bougainvillea are believed to emit positive auras while planted in the parahyangan/sanggah area of a pekarangan while negative auras are believed to appear if they are planted in front of the bale daja, a building specifically placed in the north part of a dwelling.
