अयस्मयादीनि च्छन्दसि

Words like अयस्मय etc. are valid forms in the छन्दस्।
These words being taught here in the topic relating to pada and Bha, show that they have been properly forced in the chhandas by the application of the rules of Bha and pada. Thus अयस् + मय = अयस्मय made of iron. Here the word अयस् is treated as Bha and hence the स् is not changed into र. Thus अयस्मयं वर्म iron-made coat of mail. अयस्मयानि पात्राणि iron vessels. The present form of this word is अयोमयं. In some places both these pada and Bha apply simultaneously. Thus in the word ॠक्वत् formed by ऋच् + वत्, the च् is first changed into क् by treating the word rich as a pada. Then the word ॠक् is treated as Bha, and therefore the क् is not changed into ग् before वत्. For had it been pada, the form would have been ॠग्वत् Rigvat. These irregularly formed words occur only in the chhandas or Vedic literature. Thus स सुष्टुभास ऋक्वता गणेन.
