Mahabharata Anushasna Parva Chapter 104:10

Mahabharata Anushasna Parva (Dana Dharma Parva) Chapter 104:10 A maiden too, if such, should also be avoided. A woman of the same Pravaras should also be avoided; as also one that has any malformation; as also one that has been born in the race to which one's mother belongs.[] One possessed of wisdom should never have sexual congress with a woman that is old, or one that has abandoned the domestic mode of life for entering the forest mode, or one that is true to her lord, or one whose organs of generation are not healthy or well-formed.[] It behoveth thee not to wed a woman that is of a yellow complexion, or one that is afflicted with leprosy, or one born in a family in which there has been epilepsy, or one that is low in birth and habits, or one that is born in a family in which the disease called Switra (leprosy) has appeared, or one belonging by birth to a race in which there are early deaths. Only that maiden who is endued with auspicious indications, and who is accomplished for qualifications of diverse kinds, who is agreeable and handsome, should be wedded. One should wed, O Yudhishthira, in a family that is higher or at least equal to one's own. One who is desirous of one's own prosperity, should never wed a woman that is of an inferior order or that has fallen away from the order of her birth. Carefully igniting the fire, one should accomplish all those acts which have been ordained and declared in the Vedas or by the Brahmanas.[] One should never seek to injure women. Spouses should always be protected. Malice always shortens life. Hence, one should always abstain from cherishing malice. Sleep at day-time shortens life. To sleep after the sun has risen shortens life. They who sleep at any of the twilights, or at nightfall or who go to sleep in a state of impurity, have their lives shortened. Adultery always shortens life. One should not remain in a state of impurity after shaving.[] One should, O Bharata, carefully abstain from studying or reciting the Vedas, and eating, and bathing, at eventide. When the evening twilight comes, one should collect one's senses for meditation, without doing any act. One should, O king, bathe and then worship the Brahmanas. Indeed, one should bathe before worshipping the deities and reverentially saluting the preceptor. One should never go to a sacrifice unless invited. Indeed, one may go there without an invitation if one wishes only to see how the sacrifice is conducted. If one goes to a sacrifice (for any other purpose) without an invitation and if one does not, on that account, receive proper worship from the sacrificer, one's life becomes shortened. One should never go alone on a journey to foreign parts. Nor should one ever proceed alone to any place at night. Before evening comes, one should come back to one's house and remain within it. One should always obey the commands of one's mother and father and preceptor, without at all judging whether those commands are beneficial or otherwise. One should, O king, attend with great care to the Vedas and the science of arms.
