This custom is more or less the same across all Hindu marriages across India. As Sanskrit is not understood by all here is the English translation of the Seven Vows that you have either taken or about to take soon:
First Phera
Groom: You will offer me food and be helpful in every way. I will cherish you and provide welfare and happiness for you and our children.
Bride: I am responsible for the home and all household responsibilities.
Second Phera
Groom: Together we will protect our house and children.
Bride: I will be by your side as your courage and strength. I will rejoice in your happiness. In return, you will love me solely.
Third Phera
Groom: May we grow wealthy and prosperous and strive for the education of our children. May our children live long.
Bride: I will love you solely for the rest of my life, as you are my husband. Every other man in my life will be secondary. I vow to remain chaste.
Fourth Phera
Groom: You have brought sacredness into my life, and have completed me. May we be blessed with noble and obedient children.
Bride: I will shower you with joy, from head to toe. I will strive to please you in every way I can.
Fifth Phera
Groom: You are my best friend, and staunchest well-wisher. You have come into my life, enriching it. God bless you.
Bride: I promise to love and cherish you for as long as I live. Your happiness is my happiness, and your sorrow is my sorrow. I will trust and honor you, and will strive to fulfill all your wishes.
Sixth Phera
Groom: May you be filled with joy and peace.
Bride: I will always be by your side.
Seventh Phera
Groom: We are now husband and wife, and are one. You are mine and I am yours for eternity.
Bride: As God is witness, I am now your wife. We will love, honor and cherish each other forever.
