Buddha taught that Nirvana could be attained only by cultivating Samyak Drishti (sacred vision), Samyak Vak (sacred speech), Samyak Shravanam (sacred listening), Samyak Bhavam (sacred feeling) and Samyak Kriya (sacred action). Today man is polluting his mind because of his evil vision. Once the mind is polluted, how can he expect to attain Nirvana? So, first of all he should develop sacred vision. See no evil, see what is good. Man is subjected to hardships because of his unsacred vision. Evil vision is sure to lead to sinful acts. In fact, it destroys his humanness itself. Buddha undertook various types of spiritual practices, but ultimately left all of them. He could realise the truth only by renouncing everything and by recognising unity in the plurality of the world. He could know the ultimate truth by sacrifice. This is what the Vedas say: Immortality is not attained through action, progeny or wealth. It is attained only by sacrifice. This immortality is true Nirvana. Samyak Drishti is the first step towards Nirvana. Consider all that you see as Divine. Let your vision be suffused with love. Vision filled with love is the hallmark of a true human being. – Divine Discourse, May 7, 2001
