Vajrasana is a type of yoga pose where you sit on the ground with your legs bent underneath you and your big toes touching. It's sometimes called "diamond pose" because it makes a diamond shape with your legs.
When you sit in vajrasana, you're supposed to keep your spine straight and your hands rest on your knees or thighs. This pose is often used for meditation, relaxation, or breathing exercises.
Vajrasana is considered a very stable and grounding pose because it helps you feel connected to the earth beneath you. It can also help relieve digestion problems and improve circulation in the lower half of your body.
However, it's not always comfortable for everyone to sit this way. If you have knee problems or trouble sitting on the ground, you may need to modify the pose or choose a different one that works better for you.
