[Advaita-l] Two Sankara-bhashyas on Kena Upanishad

[Sundaresan, Vidyasankar (GE Infra, Water)]

>Whether he wrote the Vakyabhashya to challenge the views of

For whatever it is worth -

Sengaku Mayeda examined both the padabhAshya and the vAkyabhAshya
on the kenopanishat and came to the conclusion that both are genuine, as
per the criteria for textual authenticity advanced by Paul Hacker and
others.

We can only speculate as to why there are two separate commentaries
here.
There is no clear way to conclude whether padabhAshya was written first
or
vAkyabhAshya was written first. My own favorite approach is to assume
that
there were probably multiple methods of textual composition. The
gItAbhAshya,
in its introductory chapter, describes itself as a deliberate act of
composition,
to clear away confusing and mutually contradictory interpretations that
had
accumulated over time. However, it is quite possible that Sankara
bhagavatpAda
did not always sit down with stylus and birch leaf to write down a
commentary.
Different lectures and discussions at different points of time may have
come to
be collected by one or more disciples. Something as simple as that could
well
account for the existence of two bhAshya-s on the kenopanishat.
