In the room of r and the penultimate letter s of the root bhrasja , there is optionally the substitute ram when an ārdhadhātuka affix follows.,
The र् and स् cease to exist and र takes their place. The substitute having an indicatory म् comes after the final vowel 1.1.49. Thus भ्रस्ज + तृ = भर्ज् + तृ = भर्ष्टा the ज being changed to ष by 8.2.36, and त to ट by 8.4.41. The other form will be भ्रष्टा; so also भर्ष्टुम् and भर्ष्टुम्, भ्रष्टव्यम् and भर्ष्टव्यम्, भ्रज्जनम् or भर्ज्जनम् ॥ But भृष्टः and भृष्टवान् by 6.1.16, in spite of this rule. The word उपदेश 6.4.37. is understood here also. The rule therefore applies to the simple root bhrasj as originally taught in the Dhatupatha, and not to any Derivative root from it. As the Intensive (यङ) is बरीभृज्यते ॥,
