Srimad-Bhagavatam: Canto 3 - Chapter 1 - Verse 19


अयं सिद्धगणाधीश: साङ्ख्याचार्यै: सुसम्मत: ।लोके कपिल इत्याख्यां गन्ता ते कीर्तिवर्धन: ॥ १९ ॥


ayaṁ siddha-gaṇādhīśaḥsāṅkhyācāryaiḥ susammataḥloke kapila ity ākhyāṁgantā te kīrti-vardhanaḥ


Your son will be the head of all the perfected souls. He will be approved by the ācāryas expert in disseminating real knowledge, and among the people He will be celebrated by the name Kapila. As the son of Devahūti, He will increase your fame.


Sāṅkhya philosophy is the philosophical system enunciated by Kapila, the son of Devahūti. The other Kapila, who is not the son of Devahūti, is an imitation. This is the statement of Brahmā, and because we belong to Brahmā’s disciplic succession we should accept his statement that the real Kapila is the son of Devahūti and that real Sāṅkhya philosophy is the system of philosophy which He introduced and which will be accepted by the ācāryas, the directors of spiritual discipline. The word susammata means “accepted by persons who are counted upon to give their good opinion.”
