Brahma Sutras 3.21
अल्पश्रुतेरिति चेत्तदुक्तम् ॥
alpa-shruter iti chet tad uktam
If it be said that Brahman is not meant because of the smallness of the space mentioned, that has already been answered.
यदि [कहा जाए] स्वल्प [आकाश] के [उल्लेख] से [दहर ब्रह्म नहीं] — तो वह [पहले] उत्तर दिया जा चुका है ॥
