Traivarṇikācāra. The mutual embrace, etc. between a man and a woman out of their own free will is called a Gāndharva marriage. This marriage takes place due to the desire of the bride and the groom, without the presence of the parents and relatives as witnesses. Therefore, it is only for the purpose of sexual enjoyment.
Rākṣasa marriage. Killing, breaking, and cutting the relatives of the bride, and while she is crying loudly, "Alas, my father, I am being abducted as an orphan," forcibly abducting the bride is called the Rākṣasa form of marriage.
Paisāca marriage. When one approaches a sleeping, intoxicated, or senseless woman in seclusion, that sinful form of marriage is called the eighth, the Paisāca.
Kanyādāna (giving away the bride) should be done at night for the Brāhma, Daiva, Ārṣa, and Prājāpatya forms of marriage. The father, having observed a fast, should give away the daughter to the fasting groom.
If the time of kanyādāna is at night, then the father should take food during the day, bathe, and recite the mantra before giving away the daughter.
Having taken food, the groom should take the bride and also accept the Sāvitrī (sacred thread). This procedure is mentioned only in the Gāndharva and Āsura forms of marriage, not in other forms.
The relatives of the bride are: the father, grandfather, brother, paternal uncle, gotra-related persons, preceptor, maternal grandfather, and maternal uncle, in order.
