So, developing his idea, in the line 1.20:
श्रद्धावीर्यस्मृतिसमाधिप्रज्ञापूर्वक इतरेषाम् ॥२०॥
1.20. śraddhā-vīrya-smṛti-samādhi-prajñāpūrvaka itareṣām
Patanjali tells that for others (itareṣām), i.e. different from those that we dealt with in the line 1.19 and whom I have referred to as the people of [spiritual] flow, the knowledge (prajna) is preceded (pūrvaka) by four factors: śraddhā, vīrya, smṛti and samādhi. Let us try to comment upon the essence of these factors. But first let us note that without some respective “fudging” this line shall not match the model of Vyasa since it postulates that Samadhi precedes the knowledge, this, in our opinion, being quite logic.
