Thila means Sesame, the black seeds that are used in cooking. Within the Hindu tradition, once a person passes away all the rituals (mainly the tharpanams) are to be performed to the departed soul. If there is something left incomplete in these rituals, it can lead to what is called ‘pitrudosham’. If the ancestors through their dissatisfied souls become angry, then life can become tough for those surviving him/her. To get relief from such oversight, Thila Homam is performed. There are specific sthalas or places where performing the Thila Homam gives the ideal benefit.
Not really, but Hindus worship their dead elders as Gods only. The forms of the departed are represented symbolically during the homam to denote that they have been invoked and they are directly witnessing the rituals being performed in their honour. If the one performing is the direct descendant, then three generations are invoked, father, father’s father and father’s father’s father (vasuroopa, rudraroopa and Aditya roopa). The same applies to the maternal side as well. If there are other relatives for whom the homam is being performed, then their names are also added.
In most cases, people approach an astrologer when they face unusual suffering in their lives for which they have no explanation. The astrologer may look into their horoscopes and make an analysis and come to the conclusion that they are afflicted with pitrudosham. The prayaschitham or atonement in such situations is to perform Thila Homam. This is how it happens on the majority of occasions.
Many people experience miraculous changes for the better, in their lives after they have performed Thila Homam. They receive the blessings of their ancestors whom they have made happy through the Thila Homam.
Thila Homam has to be professionally conducted and you must hire experts like Swarnatara spirituals to carry out the rituals and guide you.
