[taanra eka svaroopa — shree-mahaa-sankarshana taanra amsha ‘purusha’ haya kalaate ganana]
Blended reading (Sanskrit + English inline)
tāṅra eka svarūpa — śrī-mahā-saṅkarṣaṇa tāṅra aṁśa ‘puruṣa’ haya kalāte gaṇana
Balarāma’s own expansion is called Mahā-saṅkarṣaṇa, and His fragment, the puruṣa, is counted as a kalā, or a part of a plenary portion.
