Ayurveda and Yoga — The Sister Sciences
Ayurveda and Yoga are described as sister sciences in the Vedic tradition, each incomplete without the other — Ayurveda providing the science of healthy embodiment, Yoga providing the path of conscious evolution.
Ayurveda and Yoga are both rooted in the Vedic tradition and are considered sister sciences (Samskara Shastras) that mutually support and complete each other. Charaka explicitly incorporates Yoga practices — Pranayama, Dhyana, Asana, Yama, Niyama — within Ayurvedic health protocols. Vagbhata similarly recommends Yoga for maintaining health and treating disease. The complementarity is precise: Ayurveda addresses the body-mind complex from the outside in, using food, herbs, massage, and cleansing procedures to create the physiological conditions for health; Yoga addresses the same complex from the inside out, using breath, consciousness, and ethical practice to transform the subtle body. Together they offer a complete system for human flourishing at every level — physical, psychological, and spiritual. Modern integrative medicine's combining of nutrition, stress management, and mind-body practices represents a partial recovery of this sister science approach.
Yoga is the royal road to health for the mind; Ayurveda is the royal road to health for the body — they are one path with two names.
Ayurveda and Yoga rest on the same Samkhya foundation and were long practiced together: Ayurveda tends the body and the doshas so that the disciplines of the Yoga Sutras — asana, pranayama, and meditation — can proceed on a steady vehicle. The classical texts call them sister sciences, one caring for health and the other for liberation.

- What Ayurveda says about breath and prana
Ayurveda and yoga are described as two halves of one approach, one working on the body from the outside in and the other on the mind from the inside out. This is the tradition's own explanation for why its breath material is borrowed.
