At an Indian wedding, you can say these blessings (It is customary)

To the bride: “So-bhaag-ya-va-tee” bhava

To the groom: chiram jeeva bhava

The bride’s blessing is based on the word भग (bhaga – the same word used to describe God, Bhagavan). This word has rich meaning and doesn’t translate quickly into English. It means “opulence”. Opulence means potencies that are attractive, prosperous, and create felicity. 

The suffix -ya is added to get भग्य (bhagya). This modifies the word to mean that the bride “should have opulence.” Now it is a benedictive statement, “we want you to have opulence,” “we want you to prosper and be happy.”

A second suffix, -vat, is added to get भग्यवती (after declension to the appropriate noun format). This means that the wife IS the SOURCE of the bhaga (“opulence”, “prosperity”). It changes the blessing from meaning something like, “may you get rich” to “may you be rich.” This is because the wife is the source of the family’s prosperity, happiness, and fortune. She does not aquire bhagya from anyone or anywhere, she provides it from herself.

Adding the prefix “Su-” (good-) is a simple alteration to stress that the wife’s opulence should be high caliber. 

The prefix is then strengthened (“vṛddhi”) to “Sau-“, to stress that it is not just the opulence we desire for the wife, we desire her to possess the RESULT of providing opulence. This may be the most important part of the meaning, and the deepest part of the mystery of interpersonal relationships. The opulence and happiness experienced as a result of providing – lovingly, intentionally, and willingly – opulence and happiness to people one loves, is SUPERIOR in quality even to the opulence and happiness one provides. In other words, it is more pleasurable to give true love than to be the one given true love. The expression of love itself is pleasurable and does not even require any result or remuneration.

The wedding blessing to the bride is to experience this in her relationship and the new family it generates.

The blessing to the groom, by comparison, is utterly simply. “Chiram Jeeva Bhava” simply means – “you should live long.” It is almost comical in its simplicity. The meaning is, if the man has a wife who is Saubhagyavatīi, he has achieved everything there is to achieve in the world, and all that remains for him to do is to live as long as he can, so he can enjoy his wonderful fortune for as long as possible.
