Whole of nature is in a state of imbalance. When you have imbalance, this leads to confusion. If it is allowed to continue with no preventive program, in effect this eventually brings about a total chaotic state of affairs. Agnihotra helps to set right the energy cycle. Yajnya done at full moon and no moon also creates the balance that nature is missing. We must work fast. No excuses. Everyone should participate in ongoing Yajnyas.
