Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
When the city was thus endangered by the soldiers and Kalakanya, King Purañjana, being overly absorbed in affection for his family, was placed in difficulty by the attack of Yavana-raja and Kalakanya.
Purport by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
When we refer to the body, we include the external gross body with its various limbs, as well as the mind, intelligence and ego. In old age these all become weak when they are attacked by different diseases. The proprietor of the body, the living soul, becomes very sad at not being able to use the field of activities properly. In Bhagavad-gita it is clearly explained that the living entity is the proprietor of this body (ksetra-jña) and that the body is the field of activities (ksetra). When a field is overgrown with thorns and weeds, it becomes very difficult for the owner to work it. That is the position of the spirit soul when the body itself becomes a burden due to disease. Extra burdens are placed on the body in the form of anxiety and general deterioration of the bodily functions.
