By Swami Harshananda
Vyāhṛtihoma literally means ‘homa with the utterance of the vyāhṛtis’.
The vyāhṛtihoma is done during upanayāna and some other minor rites like sīmantonnayana. The three words bhuh, bhuvah and svah or suvah are called vyāhṛtis. They are generally added at the beginning of the Gāyatrīmantra.
In the vyāhṛtihoma, oblations of clarified butter are given to the accompaniment of the vyāhṛtis pronounced singly and then together.
- Sīmantonnayana is the parting of the hair upwards of the pregnant wife.
