In Jainism there isn’t any special ritual or set of steps to “make” conception happen. The tradition teaches that life, including conception, is governed by karma and the soul’s journey, not by magical formulas.

What couples should do, according to Jain dharma:

• Live with Ahimsa (non-violence) and purity in thought, word, and deed. This includes kindness to all living beings and avoiding harm in daily life.
• Follow the householder’s five vows with fidelity and self-control: non-violence (ahimsa), truthfulness (satya), non-stealing (asteya), brahmacharya (celibacy or sexual restraint within marriage), and non-attachment (aparigraha). These help create a wholesome karmic environment.
• Maintain ethical conduct and mutual respect within the marriage, supporting each other’s spiritual growth and well-being.
• Practice regular spiritual discipline that is common for lay Jain households, such as daily prayers, samayik (meditation for a fixed period), and reflection on right conduct, which helps reduce karmic buildup.
• Lead a simple, pure lifestyle: simple diet, avoidance of intoxication, and care for one’s health and cleanliness, which are conducive to a peaceful household life.

Key idea: Jain teachings emphasize that conception is not controlled by rites or external techniques but by the soul’s karmic state and the couple’s adherence to non-violence, truth, restraint, and ethical living.

If you’d like, I can summarize the relevant Jain scriptures that discuss marriage, duties of a householder, and how karma affects birth in more detail.
