Are there Christian equivalents for the four sublime attitudes or brahmaviharas of Buddhism (metta, karuna, mudita, upekkha)? The brahmaviharas are four sublime mental states recognized by Buddhism and for which there exist different meditative practices designed to cultivate them. Concretely, the brahmaviharas are:

Metta (loving kindness): wishing the happiness / well-being of all conscious beings.
Karuna (compassion): wishing the end of suffering for all conscious beings.
Mudita (sympathetic joy): rejoicing when a conscious being (oneself or other) is experiencing well-being (the opposite of envy).
Upekkha (equanimity):  &quot;To practice upekkha is to be unwavering or to stay neutral in the face of the eight vicissitudes of life—which are otherwise known as the eight worldly winds or eight worldly conditions: loss and gain, good-repute and ill-repute, praise and censure, and sorrow and happiness&quot;. I understand that it is also associated with the ability to stay in the present moment, in a state of serene mindfulness.

Question: Are there equivalent concepts in Christianity for the four brahmaviharas?
For example, my own educated guess would be that metta and karuna have probably a lot of overlap with the concept of love in Christianity, but I'm not sure if it's a perfect equivalence. And I'm not so sure if perfectly equivalent concepts can be found for mudita and upekkha either. Of course joy is definitely a thing in Christianity, as it's part of the fruit of the Holy Spirit, but what about sympathetic joy? Perhaps praising God is a form of sympathetic joy, because you feel sympathetically happy about God's good qualities? And what about the sublime state of equanimity, and all this present moment awareness and mindfulness that comes with it?
Yes, there is in Christianity something similar to the four sublime attitudes in Buddhism. Instead of four, however, there is one, and that one is composed of eight significant attitudes. Those eight attitudes are expressed in a Christian's lifestyle.
In the apostle Paul's letter to the Christians in the province of Galatia, the apostle calls that one thing &quot;the fruit of the Spirit&quot; (Chapter 6, verses 22-23 NIV):

But the fruit of the Spirit is love, joy, peace, forbearance, kindness, goodness, faithfulness, gentleness, and self-control. Against such things there is no law.

Too often, I have observed, Christians refer to the fruit of the Spirit as the fruits of the Spirit. That is unfortunate, however, because the fruit of the Spirit is what you might call a &quot;package deal.&quot; We could say quite accurately that with the fruit of God's Spirit, the whole is, in a sense, greater than the sum of the parts.
When a person is born again (or born from above) through the regenerating power of God's Holy Spirit, that person has been given all that he or she needs to live a godly life (see 2 Peter 1:3). Is there an instant transformation in that person's life? No. That transformation, referred to in Scripture as sanctification, is a lifelong process. Moreover, that process does not come about through human effort alone. The fruit of the Spirit is made possible by the Holy Spirit, not by human effort.
Salvation, of which sanctification is an important part, is a joint effort between God and every individual believer in Jesus Christ. In his letter to the Philippian Christians, Paul put it this way:

Wherefore, my beloved, as ye have always obeyed, not as in my presence only, but now much more in my absence, work out your own salvation with fear and trembling.
For it is God which worketh in you both to will and to do of his good pleasure (2:12-13 KJV, my italics).

Christians do not work for salvation. Salvation is a gift from God and not of works (see Ephesians 2:8-9), but Christians do work out their salvation in the warp and woof of life. Since God is the one who works within Christians to will and to do His good pleasure, all the credit and all the glory go to God. Christians are but vessels or channels through whom the fruit of the Spirit is fleshed out existentially.
Jesus put the same concept--different words--this way:

I am the vine, you are the branches; he who abides in Me and I in him, he bears much fruit, for apart from Me you can do nothing (John 15:5 NASV, my bolding).

In short, the Christian's primary responsibility in working out their salvation is to  be &quot;filled with the Holy Spirit&quot; and &quot;to keep in step with the Holy Spirit.&quot; Whatever attitude is needed in any given moment is a gift of the Holy Spirit. That gift comes through yieldedness, sensitivity, and obedience to the Spirit. While one Christian might struggle more with yieldedness in the area of patience than another Christian, the same Spirit is at work in both. The good news is that when a Christian fails to demonstrate the fruit of the Spirit, he or she can confess that failure God, receive forgiveness, and live to fight another day.
