तेन ते कर्मणा यक्षा गुह्यकाः क्रूरकर्मिणः / रक्षेति पालने चापि धातुरेष विभाव्यते
tena te karmaṇā yakṣā guhyakāḥ krūrakarmiṇaḥ / rakṣeti pālane cāpi dhātureṣa vibhāvyate
By that deed they became known as Yakṣas and Guhyakas, performers of fierce acts. Here it is also understood that the verbal root rakṣ means “to guard and to protect.”
