Yadavaprakasha is traditionally known as an early teacher of Ramanuja (1017-1137 CE), and they had differences in their interpretations of Advaita Vedanta. Ramanuja, in particular, emphasized the importance of devotion (bhakti) along with knowledge (jnana) in the pursuit of spiritual realization, which differed from the more intellectual and dry approach advocated by Yadava Prakasa.
Due to Ramanuja's intellectual inclination, he diverged from
the austere interpretation of the Upanishads that lacked a focus on bhakti or
devotion to God, leading to disagreements. Yadavaprakasha had intended to have
Ramanuja submerged in the Ganga River while on a pilgrimage, but Ramanuja
successfully evaded this scheme. The story about Yadavaprakasha planning harm
to Ramanuja during a pilgrimage is not universally accepted in all historical
accounts, and it may be considered as a part of the legendary narrative
surrounding Ramanuja's life.
The information about Yadavaprakasha becoming a disciple of
Ramanuja under the name Govindadasa and composing the book
"Yatidharmasamuccaya" is intriguing. However, historical accuracy can
be challenging to ascertain, and these details might be part of the
hagiographical tradition that often surrounds the lives of religious figures.
The key point to note is that Ramanuja and Yadavaprakasha
did have philosophical differences, and Ramanuja went on to develop the
Vishishtadvaita school of Vedanta, which incorporates both devotion and
knowledge in the pursuit of spiritual understanding. The historical details may
vary in different accounts, and it's essential to approach them with a critical
perspective.
