Spiritual leader Mata Amritanandamayi has said that increasing complexities of life in the modern era warrant a “revolution of the internal self” in order to shed selfishness and kindle the spirit of service. Delivering the customary address at her 60th birthday celebrations at Amritapuri, the Mata exhorted people, especially the youth, to eschew ostentation and work for the welfare of society. Rein in your desires if you desire happiness. Sadness is ephemeral, ameliorate it.
