It is about relationships

 All the yoga movements or spiritual movements 

Yoga, from sanskrit, means to connect 

Religion, from Latin, means to reconnect

They are based on relationship.

We are trying to re-establish the lost relationship to God

To break free from false attachments, false identification

To drop the association of the mind and the senses and through various connections, relationships with spiritual aspirants or teachers 

People who have walked the path or many paths

Reconnect with that is eternal 

The supersoul

Brahman 

Bhagavan 

The scriptures like Srimad Bhagavatam provide elaborate discussions on the process of reconnection 

And the spiritual cosmology 

If one is interested to know

The literature is there

The association is there

The process is there 

Paramatma is there 

Different gurus or teachers are actually different possibilities for relationship

Association.

Spiritual relationships.

Not material 

Offcourse we are in the matter. 

We accept the matter as the energy of the Lord. 

We engage the matter in spiritual service.

For the service of Lord. 

Krishna.

So it's not that they suggest something extraordinary or new as there are many within the same path and it has always been there. New is what will appear when you will connect in this moment, when you will finally have the eyes to see God and God is ever fresh. 

Offcourse there are many ways 

And some of them can take you only until some of the way.

Not the end goal. 

And if you don't know what to look for, you may feel satisfied for a while.

Offcourse you need to try it yourself.

And offcourse everyone is an individual.

There is an individual flavour but the basis is the same. 

We are trying to re-establish our relationship to the supreme.

And we're practicing this through the relationships here on Earth.

On the material world, we spiritualize everything by engaging it in Krishnas service.

We learn how to pray.

We remember our true identity.

We offer everything to God.

And he takes care of everyone as he knows best.
