The Ratnamegha-sūtra states: 'When intending to lie down, place the body on the right side with the feet overlapping, cover the body with the Dharma robe, maintain correct mindfulness and clear comprehension, and generate the notion of illumination, solely for the sake of nourishing the sense faculties and the primary elements.' The Yogācārabhūmi-śāstra asks: 'For what reason does one lie on the right side?' It answers: 'It resembles the manner of the lion king. Among all beasts, its bravery, firm fortitude, and fierceness are supreme. The bhikṣu is also like this: arousing diligent vigor, his bravery, firm fortitude, and fierceness are supreme. Due to this reason, it resembles the lion's manner of lying down. When lying down like this, the body is not agitated or disordered, mindfulness is not lost, sleep is not excessively heavy, and one does not see bad dreams.'
