Two bowls

One chopstick

What does it mean?

Edited Christmas Day:

My interpretation was a bit different from Tony’s (comment below) – I was seeing it as a commentary on how we often provide others with only part of what they need for success.  For example, technology companies will donate computers to poor schools, but not provide the training for the teachers to be able to effectively use them. 

Abundance without the tools to benefit from it.
