Śrīla Śrīdhara Svāmī quotes the following smṛti statement: rākṣaso yuddha-haraṇāt. “A Rākṣasa marriage takes place when the bride is stolen from one’s rival suitors by force.” Similarly, Śukadeva Gosvāmī himself has already said, rājñaḥ pramathya: Kṛṣṇa had to beat down opposing kings to take Rukmiṇī.
