Distractions or hobbies are bad for spiritual growth, or maybe not.
Distractions are bad for my spiritual growth.
Maybe they aren’t.
Here is a good way to help you determine the fact.
If the distraction or hobby make you be more present then it can be beneficial. While you are engaged in the event does time disappear? Do other worldly problems dissolve in the background? Does it allow you to completely “be” in the moment?
If you answered yes to these then by all means continue them. They are tools to help you experience the richness in life.
Anything that allows you to be a human being instead of a human doing will advance you on your path.
