Worship of Bodhi tree representing Krakuchchhanda Buddha

The half medallion on a rail pillar fragment features the symbolic representation of one of the seven mortal Buddhas, Krakuchchhanda. It represents a throne under a tree (the sirisha) being worshipped by devotees. The inscription reads: bhagavato kakusadhasa bodhi (i.e. the bodhi tree of Lord Krakuchchhanda). The dedicatory inscription on the shaft states that this is a gift from the donors from Purika (purikaya dakana danam).
Each of these seven Tathagatas, known also as samyak-sambuddhas, viz. Vipasyi, Visvabhu, Sikhi, Krakuchhanda, Kanakamuni, Kasyapa and Sakyamuni have their own bodhivriksha (sacred tree), the one of Krakuchhanda being Sirisa (Accacia Sirissa).
