Man and woman should live together as householders in relationship with Krsna, only for the purpose of discharging duties in the service of Krsna. Engage the children, engage the wife, and engage the husband, all in Krsna conscious duties, and then all these bodily or material attachments will disappear. Since the via medium is Krsna, the consciousness is pure, and there is no possibility of degradation at any time.

In the spiritual world, the individual soul eats, plays, and enjoys.
Chandogya Upanisad 8.12.3
The sixteen words of the Hare Krsna maha-mantra Hare Krsna, Hare Krsna, Krsna Krsna, Hare Hare/ Hare Rama, Hare Rama, Rama Rama, Hare Hare are especially meant for counteracting the sins of the age of Kali. To save oneself from the contamination of this age there is no alternative but to chant the Hare Krsna maha-mantra. After searching through all the Vedic literature, one cannot find a method of religion for this age so sublime as the chanting of Hare Krsna.
Lord Brahma
Kali-santarana Upanisad 5.6
O son of Maharaja Nanda [Krsna], I am Your eternal servitor, yet somehow or other I have fallen into the ocean of birth and death. Please pick me up from this ocean of death and place me as one of the atoms of Your lotus feet.
Sri Caitanya Mahaprabhu
Sri Siksastaka 5
When one understands that the Supreme Personality of Godhead and the individual spirit souls are eternally distinct entities, he becomes qualified for liberation and lives eternally in the spiritual world.
Svetasvatara Upanisad 1.6
One should fix one's mind on Krsna by any means. All the rules and prohibitions mentioned in the scriptures should be the servants of this principle.
Srila Rupa Gosvami
Bhakti-rasamrta-sindhu 1.2.4
The foolish with a poor fund of knowledge cannot know the transcendental nature of the forms, names, and activities of the Lord, who is playing like an actor in a drama. Nor can they express such things, neither in their speculations nor in their words.
