Vedantasara - Verse 214
Sanskrit
अनेन विघ्नचतुष्टयेन विरहितं चित्तं निर्वातदीपवदचलं सदखण्डचैतन्यमात्रमवतिष्ठते यदा तदा निर्विकल्पकः समाधिरित्युच्यते
Swami Nikhilananda's Translation
When the mind, free from these four obstacles, rests unmoved, like the flame of a lamp sheltered from the wind, as one with Absolute Consciousness, it is called the Nirvikalpa Samadhi.
