bālo ’py ayaṁ hṛdā dhatte

The qualifications of the kṣatriyas are described in Bhagavad-gītā. Two important qualifications are to have a sense of prestige and not to flee from battle. It appears that the kṣatriya blood within the body of Dhruva Mahārāja was naturally very active. If the brahminical, kṣatriya or vaiśya culture is maintained in a family, naturally the sons and grandsons inherit the spirit of the particular class. Therefore, according to the Vedic system, the saṁskāra, or the reformatory system, is maintained very rigidly. If one fails to observe the reformatory measures current in the family, one is immediately degraded to a lower standard of life.
