Jhandi Flags and the Indo-Caribbean Fight for Recognition

One of the most familiar sights in our country’s religious landscape is the Jhandi or the bamboo pole carrying flags of different colours .
Our East Indian Ancestors of Hindu faith who embarked on our shores 175 years ago brought with them the practice of hoisting and planting triangular flags placed on bamboo near homes and temples after the performance of a pooja (Hindu worship/ prayers ) . The presence of the jhandi is a sign of protection from evil forces and a sign of the devotee's piety. When planted firmly in the ground if symbolizes an upright human being, deeply rooted in spiritual values, filled with devotion and humility and intelligently making life choices that support a God centered life.
Once hoisted the flag is never broken or pulled down , the bamboo lasts a very long time and is also known to grow where it is planted. This in itself is a promise to sustain the spiritual life .  It would be interesting to know what the different colours mean.
