Definition - What does Siddhasana mean?
Siddhasana is a basic seated asana that is commonly used during pranayama and meditation practice. The name is derived from the Sanskrit words, siddha, which means "accomplished," and asana, which means "pose."
To enter the pose, begin by sitting on the ground. Bring the right heel in toward the groin and as close to the perineum as is comfortable. The arch and ball of the right foot will press lightly against the inside of the left thigh. The weight of the body rests on the right heel. Bring the left foot in, crossing it over the right foot and placing it on top of the right lower calf. The two ankles are now crossed and touching. The hands come to rest lightly on the lower thighs, palms facing downward. The eyes are relaxed and the drishti (gaze) is a couple of feet in front of the knees.
Siddhasana may also be referred to as perfect pose in English.
Yogapedia explains Siddhasana
Siddhasana stimulates both the muladhara (root) and svadisthana (spleen or sacral) chakras. It is one of the primary poses used for meditation and pranayama. Practicing siddhasana is said to regulate the flow of prana and calm the nervous system.
Siddhasana stretches the hips, knees and ankles. It also strengthens the posture and the back. The pose promotes a sense of groundedness, reduces stress and purifies the nadis (energy channels) of the body.
It is important to keep the spine straight and lengthened during siddhasana, especially during long meditation sessions or breathing exercises.
