Sana, Sanatsujata, Sanaka, Sanandana, Sanatkumara, Kapila, and Sanatana,—these seven Rishis are known as the spiritual sons of Brahman. Their knowledge comes to them of itself. These seven follow the Religion of Renunciation.
सनः सनत्सुजातश्च सनकः ससनन्दनः। सनत्कुमारः कपिल: सप्तमश्च सनातनः॥ सप्तैते मानसाः प्रोक्ता ऋषयो ब्रह्मणः सुताः। स्वयमागतविज्ञाना निवृत्ति धर्ममास्थिताः॥
