ABSTRACT
The vṛttis are called the mānasa karmas (mental work) as different from the bāhya karmas (external work) achieved in the exterior world by the five motor or active senses. These may be divided into four classes: (1) kṛshṇa (black), (2) śukla (white), (3) śuklakṛshṇa (white and black), (4) aśuklā-kṛshṇa (neither white nor black). (1) The kṛshṇa karmas are those committed by the wicked and, as such, are wicked actions called also adharma (demerit). These are of two kinds, viz. bāhya and mānasa, the former being of the nature of speaking ill of others, stealing others’ property, etc., and the latter of the nature of such states as are opposed to śraddhā, vīrya, etc., which are called the śukla karma. (2) The śukla karmas are virtuous or meritorious deeds. These can only occur in the form of mental states, and as such can take place only in the mānasa karma. These are śraddhā (faith), vīrya (strength), smṛti (meditation), samādhi (absorption), and prajñā (wisdom), which are infinitely superior to actions achieved in the external world by the motor or active senses. The śukla karma belongs to those who resort to study and meditation. (3) The śuklakṛshṇa karma are the actions achieved in the external world by the motor or active senses. These are called white and black, because actions achieved in the external world, however good (śukla) they might be, cannot be altogether devoid of wickedness (kṛshṇa), since all external actions entail some harm to other living beings.
