Śrīmad-Bhāgavatam · Text 11.24.29
Who is speaking and story frame
एष साङ्ख्यविधिः प्रोक्तः संशयग्रन्थिभेदनः ।
प्रतिलोमानुलोमाभ्यां परावरदृशा मया ॥ २९ ॥
eṣa sāṅkhya-vidhiḥ proktaḥ
saṁśaya-granthi-bhedanaḥ
pratilomānulomābhyāṁ
parāvara-dṛśā mayā
Thus I, the perfect seer of everything material and spiritual, have spoken this knowledge of Sāṅkhya, which destroys the illusion of doubt by scientific analysis of creation and annihilation.
