Natyashastra
एष एव द्वितीयेऽपि पञ्चबाणो विधिः स्मृतः । प्लुतच्छेदेऽपि तस्येष्टः सन्निपातः प्रयोक्तृभिः ॥ ५८॥
The same rule of pañcabāṇa is also considered applicable to the second syllable. Even in the case of a pluta (prolonged syllable) division, the use of sannipāta (combined movement) is favored by performers.
