Welcome to the global village!

Keep your mind clean, eyes open and ears tuned.
And roam this village with no fear 
to enrich your life.

Kashyapa A. S. Yapa

I am a simple traveler, on a shoe-string budget, 
with an insatiable thirst for knowledge, 
an incurable anger over injustice and 
an inestimable respect for nature.
