It sounds like the pain in your throat when chanting might be due to a couple of factors:
1. Throat Chakra Blockage: The throat chakra (Vishuddha) deals with communication and expression. If there's any blockage or imbalance, it can cause discomfort when you focus on energy there. The mantra you’re using is a powerful one, and if your throat chakra is blocked, it could lead to pain as energy tries to move through it.
2. Energy Overload: The mantra you're using is associated with Lakshmi, the goddess of wealth, which has a high vibration. If you're not used to handling that much energy, it can cause temporary discomfort as your body adjusts. This is common when working with powerful energies too quickly.
3. Purification Process: Sometimes, chanting can bring about a cleansing effect on your energy system. The discomfort could be a sign of old energy or blockages being released from your throat chakra, which can be physically felt as pain.
Suggestions:
Take it slow: Start with shorter sessions of chanting and gradually build up to longer ones as your energy system adjusts to the vibrations.
Throat chakra work: You might want to focus on clearing and balancing your throat chakra through additional exercises, such as breathing techniques or specific meditations.
Hydration: Make sure to stay hydrated, as it can help maintain smooth energy flow through your body and reduce discomfort.
Rest: If the pain continues, it’s okay to take breaks and let your body recover. Pushing too hard can sometimes create more tension than progress.
If the discomfort persists or feels abnormal, you may want to seek guidance from someone with more experience in energy work to help with the blockage.
