The coconut is a symbol of the heart. Before it is offered to God, all the outer fibre has to be removed. This means, spiritually, removing the Thamasic (evil) tendencies from our heart. The shell of the coconut symbolises the Rajo guna in us. The white kernel inside the coconut represents the Satwa guna. What we have to offer to God is a pure heart, without the Tamasic and Rajasic qualities such as anger, hatred and attachment. It is this purity of heart that must be manifested in making any offering to God and not the mechanical breaking of a coconut as a meaningless ritual.
