Introduction:

Sivasubramania Iyer was a renowned temple musician, and his wife was a devout and traditionally-minded woman. They lived a simple life, adhering to their cultural beliefs and customs.

Reasons for Refusing to Serve Kalam:

1. Caste Discrimination:
Sivasubramania Iyer's wife belonged to a higher caste, while Dr. APJ Abdul Kalam, the former President of India, belonged to a lower caste. In the Indian society, caste discrimination has been deeply ingrained for centuries. People from higher castes often consider themselves superior to those from lower castes and may look down upon them. This discriminatory mindset could have influenced Sivasubramania Iyer's wife's decision to refuse serving Dr. Kalam.

2. Traditional Beliefs:
Sivasubramania Iyer's wife was a devout follower of traditional customs and practices. In many orthodox families, it is believed that eating food prepared by someone from a lower caste can pollute their purity and spiritual sanctity. These beliefs stem from the ancient caste system, where purity and pollution were associated with different castes. Thus, she might have been following these traditional beliefs and considering them while refusing to serve Dr. Kalam.

3. Fear of Social Backlash:
In traditional societies, deviating from established norms can lead to social ostracization and criticism. Sivasubramania Iyer's wife might have been fearful of the potential backlash from her community if she were to serve someone from a lower caste. The fear of being perceived as breaking social norms and facing social exclusion could have influenced her decision.

4. Lack of Awareness and Exposure:
It is possible that Sivasubramania Iyer's wife had limited exposure to people from different castes and communities. This lack of interaction and understanding might have contributed to her reluctance to serve Dr. Kalam, as she may have had preconceived notions or stereotypes about people from lower castes.

Conclusion:
The refusal of Sivasubramania Iyer's wife to serve Dr. APJ Abdul Kalam in her kitchen can be attributed to a combination of deeply ingrained caste discrimination, adherence to traditional beliefs, fear of social backlash, and limited exposure to different communities. It is important to recognize and challenge such discriminatory practices to foster a more inclusive and equitable society.
