Step 1: This question is from Humayun Kabir's essay "The Unity of Indian Culture." The essay primarily focuses on the theme of "unity in diversity."
Step 2: While the central theme is unity and tolerance, a comprehensive analysis of any society must also acknowledge its challenges and negative potentials.
Step 3: The essay argues that India's unity is remarkable precisely because it has overcome immense internal differences and conflicts. This implies an acknowledgement that the underlying potential for conflict and 'hatred' exists. Therefore, Indian society's capacity for unity is a victory over its co-existing capacity for 'hatred'.
