“Although he reputedly hated the label of ‘guru’, Peter Drucker was, by any standards, the greatest management guru the world has yet seen. In 1996, the McKinsey Quarterly journal described him as the ‘the one guru to whom other gurus kowtow’ and Robert Heller described him as ‘the greatest man in the history of management’, praise indeed for a man who described himself as ‘just an old journalist’.”

Context: The truth is that Foucault knew very little about anything before the seventeenth century and, in the modern world, outside France. His familiarity with the literature and art of any period was negligible. His hostility to psychology made him incompetent to deal with sexuality, his own or anybody else’s. The elevation of Foucault to guru status by American and British academics is a tale that belongs to the history of cults.

Diwali does not end when the lights go out (2013)
Context: For the Jains, Diwali is celebrated as the joyous day on which Mahavir, the great Jain teacher, attained the eternal joy of liberation or nirvana. It is an occasion for rejoicing and gratitude for a life spent in rigorous religious search, realization and teaching centered on non-violence.
For the Sikhs, Diwali is a "day of freedom," when the Mughal Emperor, Jehangir, freed the sixth Sikh Guru (teacher), Hargobind, from prison. Guru Hargobind refused to accept his freedom unless the emperor released detained Hindu leaders. Guru Hargobind is celebrated as seeing his own religious freedom as inseparable from the freedom of others.
Even for the Hindu community, there is a confluence of many traditions connected with Diwali. Some celebrate Diwali as ushering the New Year and others as the triumph of Krishna over the evil, Narakasura.
