Mantra meditation can be an effective tool for managing anxiety, as it helps to quiet the mind and redirect your focus to a specific word or phrase. Here are some traditional mantra meditations that may be helpful for reducing anxiety:

OM SHANTI

This mantra, which means "peace be with you," can be repeated silently or out loud to promote a sense of calm and relaxation.

SO HUM

This mantra can be used to cultivate a sense of connection and calm. Inhale while silently repeating "So" and exhale while repeating "Hum."

OM NAMAH SHIVAYA

This mantra is associated with the Hindu deity Shiva and is often used in mantra meditation. It can be helpful for reducing feelings of anxiety and promoting a sense of inner peace.

You can also try simple phrases such as:

I AM CALM

This simple mantra can be repeated silently to cultivate feelings of calm and relaxation.

I AM SAFE AND PROTECTED

This mantra can help you feel more secure and grounded. Repeat it to yourself when you're feeling anxious or fearful.

THIS TOO SHALL PASS

This mantra reminds you that no feeling or situation is permanent. Repeat it to yourself when you're feeling overwhelmed.

I AM STRONG AND CAPABLE

This mantra can help you feel more confident and empowered. Repeat it to yourself when you're feeling anxious about a particular situation.

I AM IN CONTROL OF MY THOUGHTS AND EMOTIONS

This mantra can help you feel more in control of your anxiety. Repeat it to yourself when you're feeling anxious or when you notice your thoughts spiraling out of control.

I AM WORTHY OF PEACE AND CALM

This mantra can help you feel more deserving of peace and calm. Repeat it to yourself when you're feeling anxious or stressed.

The Takeaway

Remember, the most important aspect of a mantra meditation for anxiety is that it feels authentic and supportive to you. Experiment with different mantras and find the one that resonates with you and supports your well-being. Practice your mantra meditation often and with intention. Every mantra repetition is represented by one bead on your mala necklace or bracelet. For a quick session, use your bracelet and repeat your mantra once for every bead. 
Additionally, if you are struggling with anxiety, it's important to seek support from a mental health professional.
