The conditions for having good progeny in society are that the husband should be disciplined in religious and regulative principles and the wife should be faithful to the husband. In Bhagavad-gītā (7.11) it is said that sexual intercourse according to religious principles is a representation of Kṛṣṇa consciousness. Before engaging in sexual intercourse, both the husband and the wife must consider their mental condition, the particular time, the husband’s direction, and obedience to the demigods. According to Vedic society, there is a suitable auspicious time for sex life, which is called the time for garbhādhāna. Diti neglected all the principles of scriptural injunction, and therefore, although she was very anxious for auspicious children, she was informed that her children would not be worthy to be the sons of a brāhmaṇa. There is a clear indication herein that a brāhmaṇa’s son is not always a brāhmaṇa. Personalities like Rāvaṇa and Hiraṇyakaśipu were actually born of brāhmaṇas, but they were not accepted as brāhmaṇas because their fathers did not follow the regulative principles for their birth. Such children are called demons, or Rākṣasas. There were only one or two Rākṣasas in the previous ages due to negligence of the disciplinary methods, but during the Age of Kali there is no discipline in sex life. How, then, can one expect good children? Certainly unwanted children cannot be a source of happiness in society, but through the Kṛṣṇa consciousness movement they can be raised to the human standard by chanting the holy name of God. That is the unique contribution of Lord Caitanya to human society.
