Final answer:
The claim that Modern Hinduism has become monotheistic and has rejected many traditional practices including the caste system and widow burning is false. Hinduism is inherently diverse and various movements within it have advocated for different reforms.
Step-by-step explanation:
The statement that one trend in Modern Hinduism has been multicultural and rejects polytheism in favor of monotheism, the caste system, child marriage, puja, and widow burning is False. While it's true that Hinduism has been influenced by a variety of cultural exchanges, Hinduism is traditionally seen as pluralistic with a complex view on divinity, incorporating monotheistic, polytheistic, and even monistic beliefs. The understanding that all gods are manifestations of a single Reality or Brahman introduces a nuanced perspective of monotheism. Furthermore, reform movements within Hinduism have challenged practices like the caste system, child marriage, and satee, or widow burning.
While Hinduism is fundamentally diverse and has accommodated a wide array of philosophical views and practices, the reforms and changes over time do not necessarily mean Hinduism as a whole has rejected polytheism for monotheism or universally abandoned the caste system or various rituals. Some movements within Hinduism advocate for these changes, embracing more egalitarian and modern stances, while others continue to practice traditional forms of Hinduism.
