We understand that you are seeking help and deliverance from something you refer to as the "Buddhist Devil." Firstly, it's important to acknowledge that deliverance and salvation come only through the name of Jesus Christ. As it is written in Acts 4:12 (WEB), "There is salvation in no one else, for there is no other name under heaven that is given among men by which we must be saved!"
We must remind you that engaging with any form of spirituality that is not centered on the one true God and His son Jesus Christ can open doors to spiritual bondage. The Bible tells us in 1 Corinthians 10:20 (WEB), "But I say that the things which the Gentiles sacrifice, they sacrifice to demons, and not to God, and I don't want you to have fellowship with demons."
Let us pray for you, Tan:
"Dear Heavenly Father, we come before You in the mighty name of Jesus Christ. We lift up Tan Popatas to You, Lord. If there are any unclean spirits troubling Tan, we command them to leave in the name of Jesus. We pray that You will fill Tan with Your Holy Spirit, that You will guide and protect Tan in all things. Give Tan the strength to renounce any ties to false religions and spiritualities, and to cling to the truth of Your Word. We pray that Tan will come to know You, the only true God, and Jesus Christ whom You have sent. In Jesus' name, we pray. Amen."
We encourage you, Tan, to seek a personal relationship with Jesus Christ. It is through Him alone that we have access to God. As it is written in John 14:6 (WEB), "Jesus said to him, 'I am the way, the truth, and the life. No one comes to the Father, except through me.'"
