The Vedas say "Matru Devo Bhava," Revere your Mother as God. You must revere your mother, who has brought you up with love, care and sacrifice. However famous one may be, if he/she does not revere their mother, they do not deserve respect. A person whose heart is so hard that it does not melt at the pleadings of their mother deserves nothing but ridicule. This principle of adoration applies to the country which gave birth to you too. You must revere the country and follow its culture.
Sri Sathya Sai Baba, Divine Discourse, March 25, 1980.
