Radiant Heart Retreat with Kia Miller

The Radiant Heart Retreat is a seven-day yoga retreat with Kia Miller at Blue Spirit Costa Rica in Nosara, Guanacaste. It brings together yoga, breathwork, meditation, rest and community in a jungle and ocean setting, and it suits both people new to yoga and those with an established practice. If you are looking for a yoga retreat in Costa Rica with a teacher who works from direct experience, this is a week built around that kind of steady, personal practice.

The teaching draws on four traditions: Hatha, Kundalini, Tantra and Himalayan yoga. It is grounded in the science of the nervous system as well as in the intelligence of the heart.

What to Expect

The week follows a daily rhythm of yoga, breathwork, meditation and integrated rest. The aim is to restore your energy, deepen your inner connection and leave you in a more vital relationship with life. Time is set aside to listen more closely to yourself and reconnect with your inner knowing.

The retreat is held as a small-group container. That leaves room for personal practice, and for the community integration that comes from spending seven days alongside the same people. Kia's teaching moves between the physical and the subtle, so the work on the mat sits comfortably beside the quieter practices of breath and stillness.

About Kia Miller

Kia Miller is the founder of Radiant Body Yoga, a training organization offering 200-hour and 300-hour Yoga Alliance-certified teacher trainings, along with international workshops and retreats. She has 25 years of teaching experience and spends months of every year in personal sadhana and retreat, which is why she teaches from lived experience rather than theory.

She is widely recognized for her work in kriya, the integrated sets that combine asana, pranayama, mantra, mudra and meditative focus, rooted in the Kundalini tradition as transmitted through Yogi Bhajan's lineage. Her approach adapts traditional sequences for contemporary classes while keeping faith with the spiritual and energetic principles of the lineage. She works extensively with pranayama and mantra as ways to regulate the nervous system, and her emphasis falls on breath mechanics, anatomical alignment and the integration of mind, body and spirit. Many of her students go on to teach their own students around the world.

The Setting

Blue Spirit Costa Rica sits in Nosara, on the Guanacaste coast, with the ocean below and the jungle all around. The setting is part of the retreat itself: a nourishing, quiet place to practice, rest and recover a slower pace.

Before You Go

This retreat is open to all levels. The teaching meets each person at their own capacity and understanding, whether you are coming to your first yoga retreat or bringing years of practice. You do not need prior experience with Kundalini, Tantra or any of the other traditions the week draws from.
