Comprehensive rāmāyaṇa derived from the name “pūtātmā”
Rucheeka bestowed his wife Satyavati with a boon, as a result of which, Vishwamitra attained the stature of a Brahman and became purified. Therefore, Lord Rama along with Lakshmana chose to be his disciples. (Pūtaṁ vipratvaprāptyā pavitraṁ viśvāmitraṁ āpnōti śiṣyatayā prāpnōtīti pūtātmā)
