3.21

saṃkhyayā'ṣṭāvityuddiṣṭānāṃ nāmadheyānīmāni | adhamagrahaṇaṃ paiśācasya nindārtham |

(1) The Brāhma, (2) the Daiva, (3) the Ārṣa, (1) the Prājāpatya, (5) the Āsura, (6) the Gāndharva, (7) the Rākṣasa and (8) the Paiśāca, which is the eighth and the lowest.—(21)

Medhātithi’s commentary (manubhāṣya):
These are the names of the eight forms of Marriage that were referred to in the preceding verse by the number ‘eight.’

‘Lowest’— this has been added with a view to deprecate the Paiśāca form of marriage.—(21)

This verse is quoted in Vīramitrodaya (Saṃskāra, p. 846) as enumerating the different forms of marriage;—in Madanapārijāta (p. 155);—in Parāśaramādhava (Ācāra, p. 485);—in Vidhānapārijāta (p. 758);—in Saṃskāra-ratnamālā (p. 479);—in Nṛsiṃhaprasāda (Saṃskāra, p. 61a);—in Hemādri (Dāna, p. 682)—in Vyāvahāra Bālambhaṭṭī (p. 175);—in Saṃskāramayūkha (p. 99);—in Smṛticandrikā (Saṃskāra, p. 227);—and by Jīmūtavāhana (Dāyabhāga, p. 152).
