Chapter 8 · Marriage
विवाहः
युग्मेऽब्दे जन्मतः स्त्रीणां प्रीतिदं पाणिपीडनम् ।एतत्पुंसामयुग्मेऽब्दे व्यत्यये नाशनं तयोः ॥ ४१५ ॥
In the full Narada Purana (Purva Bhaga) this is chapter 56, verse 415.
In an even year from birth, taking the hand (marriage) brings love for women. For men it is in an odd year. If it is the other way round, it may bring harm to them both.
Simple meaning: A woman should marry in an even year of her age and a man in an odd year.
माघफाल्गुनवैशाखज्येष्ठमासाः शुभप्रदाः ।
Magha, Phalguna, Vaishakha and Jyeshtha are good months for marriage.
न कदाचिद्दशर्क्षेषु भानोरार्द्राप्रवेशनात् ।
No marriage, god-installing or sacred thread while the Sun moves through the ten stars from Ardra.
नास्तंगते सिते जीवे न तयोर्बालवृद्धयोः ।
Avoid marriage when Venus or Jupiter is set, very young or old, or when Jupiter is in Leo.
