¹ According to Manu-smṛti and the other dharma-śāstras, there are particular nights when a married couple can engage in sexual union, failing which, one loses his pious credits and so on. This is the ordinary standard for sinless sensualists engaged on the platform of karma-kāṇḍa. However, those who are seeking liberation from material existence, and that too within one very lifetime, are even more careful in this regard and avoid all forms of sense enjoyment—even those permitted in the dharma-śāstras—except those prescribed as barely required by Vedic scriptures. Such increasingly sāttvika souls are naturally averse to sinful sense enjoyment, but they also take steps to decrease their engagement in sinless sense enjoyment. They only engage in sexual activities within dharma and that too only to conceive children with the view of growing them up to become pure devotees of the Supreme Personality of Godhead. They cultivate the mode of goodness as noted in Bhagavad-gītā 13.8-12.
