Kundalini Yoga Instructor
Raquel embarked on her transforamtive journey with Kundalini Yoga in 2019 after a health issue led her to realize the importance of self-care and the need to prioritize her well-being to avoid falling prey to illness. Kundalini Yoga, a technology and yoga of awareness, helped her to delve deeper into her inner self, and began to notice certain patterns that were no longer serving her.
As she implemented her daily practice, she began to operate from a state of calm and peach which enabled her to see things from different perspectives and speak her truth with more confidence. Unexpectedly, she began to notice physical changes in her body as she tapped into her internal medicine cabinet through conscious breath.
Driven by her transformative experience (and now science), Raquel desires to share the peace and optimal state of being with as many humans as ppossible. She believes that Kundalini Yoga is not just a physical practice but a way of life that allows us to access our inner power and potential.
