тнРWhen emperuman goes out on foot, Aadhiseshan will be his umbrella,
тнРWhen┬аemperumAn┬аdesires to sit, Adhiseshan will be his throne,
тнРWhen emperuman desires to stand, Adhiseshan will be his sandals,
тнРIn the expansive milk ocean, when emperuman wants to rest awhile, Adhiseshan becomes his soft mattress that floats,
тнРIf emperuman wants to see objects, Adhiseshan will become auspicious lamp,
тнРWhen emperumAn desires to recline, he will become the pillow,
тнРIf emperuman desires in his divine mind to wear a beautiful dress, Adhiseshan will be his yellow silky dress which indicates that emperuman is the supreme entity...
Just as golden bar can be converted into ornaments as we desire, Adhiseshan also transforms into umbrella, throne, sandals, float, lamp, divine dress, pillow etc while carrying out service to emperuman and Piratti.
Adiseshan, as name denotes, supreme seshan to serve emperuman... Has taken several forms, among which he has incarnated as an avatara purusha taking main role in each yuga as follows :
Kritha yuga - Adiseshan
Thretha yuga - Lakshman
Dwapara yuga - Balaram
Kalki yuga - Ramanuja
