According to the Vaastu Shastra, it is auspicious in for homes and offices to be situated in the northeast. North is the direction wealth resides, associated with Kubera, while East is the direction where knowledge resides, associated with Indra. For this reason, Ishana symbolizes the culmination of both knowledge and wealth.
Īśāna is one of the twelve devas who guard the directions. He is a chief among the gods of Paranirmitavaśavarti, the sixth heaven of the kāmadhātu. While texts such as the Shí Èr Tiān Gōng Yí Guǐơ (十二天供儀軌) and the Mahāprajñāpāramitōpadeśa refer to him as Maheśvara, he is in fact a separate figure.
According to the Ainōshō, there is a theory that this deity is synonymous with Pāpīyas as well as the Shinto deity Izanagi. The Jinnō Shōtōki also states that there is a theory that the names of Japan's primordial creator gods Izanagi and Izanami are the same as the Sanskrit names Īśāna and Īśānī.
Īśāna is often depicted with three eyes and having a fierce expression.
He holds a trident in his right hand and a cup in his left hand. His vehicle is an ox.
