Jesus taught the resurrection not reincarnation.
Matthew 22:23-29 The same day came to him the Sadducees, which say that there is no resurrection, and asked him, Saying, Master, Moses said, If a man die, having no children, his brother shall marry his wife, and raise up seed unto his brother. Now there were with us seven brethren: and the first, when he had married a wife, deceased, and, having no issue, left his wife unto his brother: Likewise the second also, and the third, unto the seventh. And last of all the woman died also. Therefore in the resurrection whose wife shall she be of the seven? for they all had her. Jesus answered and said unto them, Ye do err, not knowing the scriptures, nor the power of God.
Buddhist's teach Karma not justice or grace.
The bible teaches that a man reaps what he sows in this life or after death.
Luke 14:12-14 Then said he also to him that bade him, When thou makest a dinner or a supper, call not thy friends, nor thy brethren, neither thy kinsmen, nor thy rich neighbours; lest they also bid thee again, and a recompence be made thee. But when thou makest a feast, call the poor, the maimed, the lame, the blind: And thou shalt be blessed; for they cannot recompense thee:
for thou shalt be recompensed at the resurrection of the just.
Buddhist teachings on Karma being reincarnated over and over until one becomes free from rebirth is not biblical.
Buddhist rituals are not Christian but alien to what Christ taught.
1 Corinthians 10:20 But I say, that the things which the Gentiles sacrifice, they sacrifice to devils, and not to God: and I would not that ye should have fellowship with devils.

"One's lot in life, according to those who believe in reincarnation, is based on the law of karma. This law says that if bad things happen in one's life, this is an outworking of bad karma. If good things happen in one's life, this is an outworking of good karma.
"Karma" refers to the "debt" a soul accumulates because of good or bad actions committed during one's life (or past lives). If one accumulates good karma by performing good actions, he or she will be reincarnated in a desirable state. If one accumulates bad karma, he or she will be reincarnated in a less desirable state. In Shirley MacLaine's book Out on a Limb we are told, "Reincarnation is like show business. You just keep doing it until you get it right."
Some people twist the Scriptures and say that Jesus Himself taught reincarnation or "cyclical rebirth." In Matthew 11:14, for example, Jesus said, "And if you are willing to accept it, [John the Baptist] is the Elijah who was to come." Likewise, in John 3:3 Jesus said, "I tell you the truth, no one can see the kingdom of God unless he is born again."
But these passages, rightly interpreted, do not support reincarnation. Matthew 11:14 does not really teach that John the Baptist was a reincarnation of Elijah. Luke 1:17, an important cross reference, tells us that the ministry of John the Baptist was carried out "in the spirit and power of Elijah." Moreover, reincarnationists conveniently forget that John the Baptist, when asked if he was Elijah, flatly answered, "No!" (John 1:21).
The bible teaches that the wages of sin is death and that "all have sinned".
That means no one has "good karma".
Romans 3:23
For all have sinned, and come short of the glory of God;
Romans 5:12 Wherefore, as by one man sin entered into the world, and death by sin; and so death passed upon all men,
for that all have sinned:
A person can only be saved by grace through faith and those are "gifts" not wages.
Ephesians 2:8 For by grace are ye saved through faith; and that not of yourselves: it is the gift of God:
Ephesians 2:9 Not of works, lest any man should boast.
2 Timothy 1:8-10 Be not thou therefore ashamed of the testimony of our Lord, nor of me his prisoner: but be thou partaker of the afflictions of the gospel according to the power of God;
Who hath saved us, and called us with an holy calling, not according to our works, but according to his own purpose and grace, which was given us in Christ Jesus before the world began, But is now made manifest by the appearing of our Saviour Jesus Christ, who hath abolished death, and hath brought life and immortality to light through the gospel:
Jesus has abolished death. We don't die over and over again until we get it right.
Hebrews 9:27 And as it is appointed unto men
once to die, but after this the judgment:
Buddhist teachings are the antithesis of what Christ taught and are the doctrines of devils.
Sinners are saved by grace.
