I do feel that verses ten and eleven in Chapter Two of the Yoga Sūtra offer a directional shift as an inspiration for undertaking the transitional commitment from Kriyā Yoga towards Aṣṭāṅga Yoga.
“These (Kleśa) are subtle and are
overcome by going back to their origin.”
Yoga Sūtra Chapter Two verse 10“This fluctuation
(the rise and fall in their perpetual potency to ‘take over’)
is overcome by meditation.”
Yoga Sūtra Chapter Two verse 11
For me, these two verses are an essential reflection in the transition from the integration of Bāhya Sādhana, towards the cultivation of Antar Sādhana. Furthermore, when considering this deepening of our Sādhana from Bāhya towards Antar, these verses also re-mind me of the simple yet heartfelt teaching inherent in Chapter One.
