Markandeya said : The fire named Bharata was bound by severe rules of asceticism; Pushtimati is his another name; when he is satisfied he grants pushti (development) to all creatures and therefore he is called Bharata.
मार्कण्डेय उवाच गुरुभिर्नियमैर्युक्तो भरतो नाम पावकः। अग्निः पुष्टिमतिर्नाम तुष्टः पुष्टिं प्रयच्छति। भरत्येष प्रजाः सर्वास्ततो भरत उच्यते॥
