In plain words
The previous section described the severe distress of famine, where people were reduced to eating impure scraps. To avoid such suffering and to gain food, the text now introduces the canine udgītha—the Sāman chant observed by dogs. Baka Dālbhya, also known as Glāva Maitreya, went outside the village to a secluded place near water to study the Vedas.
Close to the Sanskrit
In the previous section, the miserable condition caused by the lack of food—characterized by eating stale food left over from leftovers—was stated. Lest that happen, for the acquisition of food, thereafter the udgītha seen by dogs, namely the singing of the Sāman, is introduced. There, Baka by name, the offspring of Dalbha, i.e., Dālbhya, or Glāva by name, the offspring of Mitrā, i.e., Maitreya... went forth outside the village for scriptural study.
