As always, you’ll get better answers if you’re not anonymous.

“The ordinances of the endowment embody certain obligations on the part of the individual, such as covenant and promise to observe the law of strict virtue and chastity, to be charitable, benevolent, tolerant and pure; to devote both talent and material means to the spread of truth… to maintain devotion to the cause of truth; and to seek in every way to contribute to the great preparation that the earth may be made ready to receive her King, the Lord Jesus Christ. With the taking of each covenant and the assuming of each obligation a promised blessing is pronounced, contingent upon the faithful observance of the conditions” — James E Talmage, The House of the Lord

Those are three answers, straight out of official manuals, so while anyone is free to disagree with them, they’re pretty good as sources go.

As with everything in the temple, the answer can be a little anti-climactic to those who are expecting something new or even suspicious. They’re powerful in their simplicity, as are all things spiritual, because spirituality is largely correlative to reverence for most humans; but in the end you are simply promising to be obedient to the Lord and keep His commandments, which He said was what we would do if we love Him. These include being willing to sacrifice everything for Him if necessary, especially unholy and inappropriate things, to keep ourselves chaste and pure, and to dedicate our time and talents and other means to serving God and our fellow man.

It seems to me that those seem to build on each other. Love God with all of our heart, might, mind, and strength, keep His commandments, be willing to live for Him and be willing to die for Him - and to really really be willing to live for His causes and be really really willing to die for His causes.
