Yoga Sūtra Chapter One verse 44
एतयैव सविचारा निर्विचारा च सूक्ष्मविषय व्याख्याता ॥४४॥
etayā-eva savicārā nirvicārā ca sūkṣma-viṣayā vyākhyātā ||44||
thus the process of subtle reflection,
without and with refinement,
for subtle objects is explained.
Commentaries and Reflections
Commentary by Paul Harvey:
By these same steps the process of reflection on a subtle object is explained,
firstly in an unrefined stage of reflection,
intermixed with words, purpose, knowledge and imagination around that object,
and then in a refined stage,
with a purification of memory,
so as if empty of its own content;
in the refined stage of reflection,
only the true nature of the subtle object shines forth.
