People choose different spiritualities. Spirituality can be seen as the link between our existence in the physical world and what we consider to be the source of everything.
Some perceive the source outside themselves, for example they believe in God and their religion is the link to this source.
Some perceive the source within themselves and see themselves as their own source. In this case any exercise allowing them to go to the source is the way to experience being the source.

When it comes to chakras, our root chakra represents our connection with Mother Earth. Our roots, like those of trees, connect us to the earth to give us the stability and nourishment we need to feel grounded, confident, at home on Earth.
Our crown chakra represents our connection with what we consider to be the source of everything. It represents our source of direction.

For us, the crown chakra also represents collective consciousness, unity, empathy, becoming "one" with another being, or all beings.

For those who perceive the source outside, God for example if we take the example of Roman Catholics, the fact of going to Mass on Sunday allows them to have this sense of unity with their community. It is their means of having this contact with the source.

For those who perceive the source within, deep meditation can, for example, allow them to go deeper, to the source.

The goal is not to remain in this space, in the same way that it is not to live in one's place of worship. The goal is to keep this contact with the source, to know that it is there.
Like our parents with whom we no longer live but with whom we go to have lunch sometimes on Sundays.
Feet on the ground, head in the stars, and in between, Sunday meal :)
