Padukasahasra 28.4

28.4

anyeṣu satsvapi narendrasuteṣu daivā-dbhraṣṭaḥ padādadhikaroti padaṃ padārhaḥ |
prāyo nidarśayati tatprathamo raghūṇāṃ tatpādayoḥ pratinidhī maṇipāduke vā ||

Even when other sons of the king exist, one who is fallen by fate from his position
appropriates that position if he is worthy of it;
this is illustrated mostly by the first of Raghus,
or else by the jewelled sandals, the representatives of his feet.
