CC Adi 1.105

vaktavya-bāhulya, grantha-vistārera ḍare
vistāre nā varṇi, sārārtha kahi alpākṣare

vaktavya—of words to be spoken; bāhulya—elaboration; grantha—of the book; vistārera—of the big volume; ḍare—in fear; vistāre—in expanded form; nā—not; varṇi—I describe; sāra-artha—essential meaning; kahi—I say; alpa-akṣare—in few words.

I purposely avoid extensive description for fear of increasing the bulk of this book. I shall describe the essence as concisely as possible.
