SB 5.10.2

Although Jaḍa Bharata was forced to carry the palanquin, he did not give up his sympathetic feelings toward the poor ants passing on the road. A devotee of the Lord does not forget his devotional service and other favorable activities, even when he is in a most distressful condition. Jaḍa Bharata was a qualified brahmana, highly elevated in spiritual knowledge, yet he was forced to carry the palanquin. He did not mind this, but while walking on the road, he could not forget his duty to avoid killing even an ant. A Vaisnava is never envious or unnecessarily violent. There were many ants on the path, but Jaḍa Bharata took care by looking ahead three feet. When the ants were no longer in his way, he would place his foot on the ground. A Vaisnava is always very kind at heart to all living entities. In His sahkhya-yoga, Lord Kapiladeva explains: suhrdaḥ sarva-dehinam. Living entities assume different bodily forms. Those who are not Vaisnavas consider only human society worthy of their sympathy, but Krsna claims to be the supreme father of all life forms. Consequently the Vaisnava takes care not to annihilate untimely or unnecessarily any life form. All living entities have to fulfill a certain duration for being encaged in a particular type of material body. They have to finish the duration allotted a particular body before being promoted or evolved to another body. Killing an animal or any other living being simply places an impediment in the way of his completing his term of imprisonment in a certain body. One should therefore not kill bodies for one's sense gratification, for this will implicate one in sinful activity.
