Kapila Muni enunciated in this material world the Sāṅkhya philosophy, which is a strong boat with which to cross over the ocean of nescience. Indeed, a person eager to cross the ocean of the material world may take shelter of this philosophy. In such a greatly learned person, situated on the elevated platform of transcendence, how can there be any distinction between enemy and friend?
Srimad Bhagavata Purana
श्रीमद्भागवतमहापुराणम्
मूल श्लोकः
न साधुवादो मुनिकोपभर्जिता नृपेन्द्रपुत्रा इति सत्त्वधामनि । कथं तमो रोषमयं विभाव्यते जगत्पवित्रात्मनि खे रजो भुवः
na sādhuvādo munikopabharjitā nṛpendraputrā iti sattvadhāmani | kathaṃ tamo roṣamayaṃ vibhāvyate jagatpavitrātmani khe rajo bhuvaḥ
