Book excerpt: The Hindu Dharma (known as Hindu religion by the west) has been the subject of many a debate over the ages. Some scholars do not agree with the interpretation of others. In such an environment, Vishwanathan ignites the curiosity of the common man about Hinduism and shares information on how the caste and class need to be understood through the Upanishads resulting in a true understanding of the Manusmriti. Vishwanathan clears the air about all misinterpretations that are commonly available to us, by referring to the ancient texts, explaining and analysing it for us. A very interesting read, to say the least.
