Nihilism usually have a negative connotation to it which comes with an irreverence for values and virtues on the notion that they are abstractly contrived.
But virtues in Hinduism are qualities that automatically arises with meditation or awareness, and vice versa.
When even one virtue becomes our nature, the mind becomes clean and tranquil. Then there is no need to practice meditation; we will automatically be meditating always. ― Swami Satchidananda
Nihilism is usually associated with violent ideologies like anarchism, communism and nazism as it provides the moral stimulus for total negation of accepted values, virtues, and norms needed for effective implementation of the ideological agenda.
“If we present a man with a concept of man which is not true, we may well corrupt him. When we present man as an automaton of reflexes, as a mind-machine, as a bundle of instincts, as a pawn of drives and reactions, as a mere product of instinct, heredity and environment, we feed the nihilism to which modern man is, in any case, prone. I became acquainted with the last stage of that corruption in my second concentration camp, Auschwitz. The gas chambers of Auschwitz were the ultimate consequence of the theory that man is nothing but the product of heredity and environment; or as the Nazi liked to say, ‘of Blood and Soil.’ I am absolutely convinced that the gas chambers of Auschwitz, Treblinka, and Maidanek were ultimately prepared not in some Ministry or other in Berlin, but rather at the desks and lecture halls of nihilistic scientists and philosophers.” - Viktor Frankl
