In American Sign Language (ASL), the phrase "thoughts and prayers" can be signed by using the signs for "think" and "pray." Here's how you can sign it:
Sign "THINK" by touching your forehead with the fingers of your dominant hand (usually the index and middle fingers) and moving them in a circular motion.
Sign "PRAY" by bringing your hands together in a praying position in front of your chest.
So, you would sign "thoughts and prayers" by combining the signs for "THINK" and "PRAY" in that order.
