4.1 In the beginning of creation, with a veiw to infusing vigour into the Ksatriyas who are the protectors of the world, aham, I; proktavan, imparted; imam, this; avyayam, imperishable; yogam, Yoga, presented in the (preceding) two chapters; vivasvate, to Vivasvan, the Sun. Being endowed with this power of Yoga, they would be able to protect the Brahmana caste. The protection of the world becomes ensured when the Brahmanas and the Ksatriyas are protected. It (this Yoga) is avyayam, imperishable, because its result is undecaying. For, the result-called Liberation-of this (Yoga), which is characterized by steadfastness in perfect Illumination, does not decay. And he, Vivasvan, praha, taught (this); manave, to Manu. Manu abravit, transmitted (this); iksvakave, to Iksvaku, his own son who was the first king. [First king of the Iksvaku dynasty, otherwise known as the Solar dynasty.]
