When asking if a discipline or practice is biblically sound the key question is not about the name of the discipline, but rather how that discipline is carried out or implemented.
The Bible speaks to many of these directly so the best test would be to identify the applicable passages and test the practice under consideration against the principles identified. A basic example I can relate is prayer.
In Luke 11:1-13 the 12 disciples ask Jesus to teach them to pray. Here is the passage:
Now Jesus was praying in a certain place, and when he finished, one of
his disciples said to him, “Lord, teach us to pray, as John taught his
disciples.” 2 And he said to them, “When you pray, say:
“Father, hallowed be your name. Your kingdom come. 3 Give us each day our daily bread, 4 and forgive us our sins, for we ourselves forgive everyone who is indebted to us. And lead us not into temptation.”
5 And he said to them, “Which of you who has a friend will go to him
at midnight and say to him, ‘Friend, lend me three loaves, 6 for a
friend of mine has arrived on a journey, and I have nothing to set
before him’; 7 and he will answer from within, ‘Do not bother me; the
door is now shut, and my children are with me in bed. I cannot get up
and give you anything’? 8 I tell you, though he will not get up and
give him anything because he is his friend, yet because of his
impudence he will rise and give him whatever he needs. 9 And I tell
you, ask, and it will be given to you; seek, and you will find; knock,
and it will be opened to you. 10 For everyone who asks receives, and
the one who seeks finds, and to the one who knocks it will be opened.
11 What father among you, if his son asks for a fish, will instead of
a fish give him a serpent; 12 or if he asks for an egg, will give him
a scorpion? 13 If you then, who are evil, know how to give good gifts
to your children, how much more will the heavenly Father give the Holy
Spirit to those who ask him!”

After reading this passage we now have one biblical standard by which to examine a person's praying practice. In Jesus' model prayer we see:
- Praise and worship
- Asking for God's will to be done
- Asking the Lord for what we need to live
- Ask for forgiveness
- Ask for the ability to forgive others
- Ask for protection from temptation
Jesus then goes to speak about the reasoning behind the prayer, why we are to ask for God to grant us certain things.
This is a prime passage to use to determine if you are praying properly and in a way that pleases the Lord. Now, as a word of warning as in most things covered in the Bible this is not the only place a topic is addressed. We must consider the Bible's commentary on a topic wholly and consistently. In trying to answer questions like these we cannot simply pick a choose what passages we use.
