character (svarūpa or prakrti) which includes mor-

medicinal plants constitute the branch known as

sattva). Durga interprets 'sattva' as
'existence of gender and number. He further quotes from
Brhaddevatā (1.42) as follows-
'शब्देनोच्चारितेनेह येन द्रव्यं प्रतीयते ।
तदक्षरविधौ युक्तं नामेत्याहुर्मनीषिणः ॥'
 
('Nāma' is defined by the learned as the word which on

alphabets. )
