He preaches a foundation of five basic values: Truth, Right Conduct, Peace, Love and Non-violence. He teaches the unity of all major world religions and says that they all lead to God. Critics, including skeptic Basava Premanand and the former follower Welsh pianist David Bailey, claim that these materializations are done by sleight of hand and say that this can be verified with videos available on the internet. Most vehement criticism since the year 2000 are the allegations of inappropriate sexual relations with young men. Followers and proponents, consider the evidence of wrongdoing against Sathya Sai Baba to be insufficient, misrepresented or outdated. His followers and the organizations that he has founded are involved in many service projects around the world, for example, free education in schools, free healthcare provided through state-of-the-art hospitals near Baba's main ashram and in Bangalore and water projects serving thousands in the Indian states of Andhra Pradesh and Tamil Nadu. In Puttaparthi, the place where Baba was born and still lives, originally a small village, one can now find a university, Chaitanya Jyoti (World Religions Museum), planetarium, a railway station, a super specialty hospital and more. High ranking Indian politicians, like the current president Dr. Abdul Kalam, Manmohan Singh (then the finance minister), and Atal Vajpayee (then the prime minister) have been official guests at the ashram in Puttaparthi.
