Definition - What does Vajrasana mean?
Vajrasana comes from the Sanskrit words vajra, meaning “thunderbolt,” “diamond-like,” or “adamant/firmness,” and asana, meaning “posture.”
To enter the pose, begin by kneeling on the floor. The hips and buttocks are at first lifted off the legs, the inner knees and thighs together, the tops of the feet on the floor and toes untucked. Lower the hips and buttocks to sit on top of your heels on an exhale. Feet, ankles, shins, and knees should remain in one line. Sit up tall and activate the core muscles, drawing the shoulders down the back and away from the neck and ears. Point the tailbone to the floor, arms relax on the tops of the thighs or along the sides of the body, and palms are down.
Practitioners can sit and enjoy the pose as long as is comfortable, being mindful of the breath. This pose should be practiced very cautiously or not at all by those with a knee problem, as it is a stretch in the knees.
Vajrasana is also known as thunderbolt pose.
Yogapedia explains Vajrasana
Vajrasana is a seated yoga pose that assists in gently stretching the legs, from thighs to knees to feet, and is believed to assist in digestion. It is often used as a meditative pose or transitional pose between other asanas.
Vajrasana encourages tranquility by clearing the mind and entering into a state of rest, which is why it is often used as a meditative pose or for pranayama and/or sadhana practice. Outside of a yoga spiritual practice, this asana is also used by other religions as a prayerful pose.
