etad evīdṛśaṃ sūkṣmaṃ brahmacaryaṃ vidur budhāḥ | viditvā cānvapadyanta kṣetrajñenānudarśitāḥ ||
The wise know precisely this to be the subtle essence of brahmacarya. Having understood it, and having been guided by the Knower of the Field (kṣetrajña), the awakened men of self-knowledge take it up and continue to live by it—steadfastly maintaining that disciplined way of life.
ब्राह्मण उवाच
True brahmacarya is described as a subtle, inward discipline recognized by the wise; when one is instructed by the kṣetrajña (the inner knower/self), one understands its real nature and steadily lives according to it.
A brāhmaṇa speaker is explaining the refined meaning of brahmacarya, emphasizing that awakened, self-knowing persons—after receiving right guidance—undertake and continually maintain this disciplined way of life.
