According to Lee, some Qi Gong masters simply have an innate sense to see energy. Other masters perceive qi with other senses like feel or touch, some Qi Gong practitioners hear energy. Different practitioners have different heightened perceptions. Depending on who you are and how you entered this world, some may see qi easily without practice, others have to practice a lifetime, and some never gain the ability to see "energy." It just depends on your gifts.
Lee suggests a classic book called, "Hands of Light." by Barbara Brennan. She shares some great practices and exercises to attune your senses into energy.
Have fun and continue to spread positivity and kindness.
