The world is both real and unreal. In advaita, Sankaracharya opined two realities. Absolute (Parmarthika - final meaning) and Vyavaharika (Pragmatic - worldly perception). So, 'Samsara' is real if we do not go into philosophical details (Vyavaharika Satya). If we do that, then 'Samsara' does not exist (Parmarthika Satya). Dharma exists only in Vyavaharika. In Paramarthika, Brahman only exists.Is dualism a real appearance in the world? Is it only a seeming appearance?
Our main difference as Buddhists and Jains is our rejection of the Vedas, ..
As for Vedas, we need not worry about that. Hindus give no more than lip-service to Vedas. We do not have animal sacrifices now. In practice, what we do is puja and bhakti (devotion), something that Mahayana adopted from us. Jains have their own cosmology, but again, we are not differ in practice. We worship the deities, only a few of whom are mentioned in the Vedas. They were adopted during the Aryan/indigenous people integration - Rudra combining with Shiva, Vishnu combining with the regional Gods in India including Rama and Krishna, and Sarawati. Buddhist worship Buddha and various Bodhisattvas.
Buddha is worshiped among Hindus too as the ninth and the latest avatara of Lord Vishnu. You would hardly find a house without an idol of Buddha among the educated Hindus. Names of Buddha are given to millions of children (including my own son). So basically, there is no difference between Hinduism and Buddhism - the noble Eight-fold path is 'dharma' for a Hindu too. As for philosophies, there are many in Hinduism as well as Buddhism and Jainism. We have accepted existence of deities and soul as the people are still not enlightened / advanced enough to abandon these ideas as they were not in Buddha's time. That is why Buddha too talked about heaven, hell and rebirth, although his meaning was very different from the usual.
