In order that they may get the auspicious sight of a deity early in the morning, Hindus generally plant the Umbar and Tulsi trees in front of their houses, and worship them daily. The juice of the root of the Umbar has a cooling effect, and hence it is freely used in cases of measles or itch. Its sap is also used as medicine for swellings. It is very pleasant to sit under the shade of this tree, and as it is believed that the god Dattátraya resides beneath this tree, it is held very sacred by the Hindus. [724] Pipal--The Pipal tree is considered very sacred because it is believed that the god Brahma resides in the roots, the god Vishnu in the trunk, and the god Shiva on the top of this tree. Persons who make a particular vow or have any objects to be fulfilled worship the Pipal tree, and walk round it several times every day. [725] The evil spirits Sambandh, Devachár, Munja, and Vetál haunt the Pipal tree. These spirits are considered to be the servants of the god Shiva. It is also believed that persons who worship and walk round this tree daily are not affected by those spirits. The Pipal tree is specially worshipped at dawn on Saturday as it is considered that the gods Brahma, Vishnu, and Mahesh or Shiva happen to be there at that time. [726] Vad or the Banian tree--A prince named Satyawán died of snakebite under the Vad tree. His wife named Sávitri, who was very chaste and dutiful, requested Yama, the god of death, and succeeded in securing from him the life of her husband Satyawán. As the prince Satyawán returned from the jaws of death under the Vad tree, this tree was specially worshipped by her, and it is therefore believed that Sávitri has ever since then been responsible for the practice of worshipping the Vad tree by women for the purpose of securing a long life to their husbands. [727] It is also believed that the god Vishnu takes shelter under the Vad at the time of the general destruction of the world. The worship of this tree is similar to that of the other deities, and women take turns around it at the close of the worship or puja. [728]
