How long should each stage be held in meditation?
The duration for each stage can vary depending on individual comfort and progress. Generally, the guidelines are:

1. Stage 1: 1-5 minutes
2. Stage 2: 1-30 minutes
3. Stage 3: 5-30 minutes
4. Stage 4: 1-5 minutes

6. Stage 6: As long as happy emotions (sukha) persist

It's essential to remember that the goal is to reach a state of access concentration, and practitioners should move on to the next stage only when they have achieved stability and deep concentration in the previous one.
