Here is an Aham Brahmasmi meditation from The Chopra Center:
Aham Brahmasmi (ah-HUM brah-MAHS-mee) is a Sanskrit sutra whose English translation is “the core of my being is the ultimate reality, the root and ground of the universe, the source of all that exists.” When we repeat this sutra and let it resonate deep within, we expand our awareness of our eternal, unbounded nature. Here is a sutra practice you can use right now:
Begin by meditating for a few minutes, then imagine that you are a crystal bead. You reflect the light of every being in the universe, and your light is reflected in them. Silently repeat the words “Aham Brahmasmi” and continue to envision yourself as a beautiful jewel, reflecting and absorbing the light of the entire universe. Rest in the silence and feel the expansiveness of your being – an expression of the infinite field of intelligence and all possibilities.
