Final answer:
The question relates to the historical roles of women in Indian society, specifically the concept of Sambandham. Sambandham describes a type of relationship in Kerala, but it is not associated with the idea of women having multiple 'night visitors'. Women's roles and autonomy have changed significantly throughout Indian history, affected by cultural shifts such as the increasing patriarchy and practices like sati.
Step-by-step explanation:
The question appears to inquire about the historical and cultural practices concerning women in Indian society, specifically regarding the concept of Sambandham. Historically, Sambandham refers to a marriage-like relationship among certain Hindu castes in the Kerala region of India. However, the practice of women having multiple 'night visitors' or partners is not directly tied to the term Sambandham or the historical context provided. It is important to note that over time, the roles and autonomy of women in Indian society have fluctuated, from periods where women could attain high levels of enlightenment and learning to eras where they were confined to more subservient roles, as highlighted by the ritual practice of sati. The question may be based on a misinterpretation or confusion about historical practices and does not reflect a well-documented or common cultural practice, so it is not possible to determine a number for how many 'night visitors' women may have had throughout their lives in the context of Sambandham or similar traditions.
