The Sarva Siddhanta Sangraha is a work by the Advaita philosopher Adi Shankaracharya describing the views of various schools of Indian philosophy which existed in his time. One of the schools he discusses is the Vaisheshika school, which subscribed to a philosophy of atomism. Now the Vaisheshika school believed that consciousness was only a property of the soul when it is in Samsara, and that after it has attained Moksha, it loses all consciousness and becomes like an inanimate object. In this excerpt from the Sarva Siddanta Sangraha, Adi Shankaracharya says that if the Vaisheshika school was correct then Moksha wouldn't be very desirable:
I choose to be a fox in the beautiful Vrindavana to that altogether blissless salvation of soul deliverance, which has been taught by the Vaisheshika, who, by means of the sacrifices prescribed in the Vedas and by means of the grace of the Lord, wishes to attain with great effort the (altogether feelingless) state of a swoon, a condition of existence similar to that of a stone.
I'm interested in the part in bold, about preferring to be born as a fox in Vrindavana. My question is, did Krishna ever interact with any foxes during his time in Vrindavana? Or is Adi Shankaracharya just extolling the glory of living in proximity to Krishna, whether one interacts with Krishna or not?
Are there any commentaries on the Sarva Siddhanta Sangraha which shed light on this?
