Mind.

Most religions are centered in the mind.

Christianity is a set of beliefs.

Judaism is the practise of the Law.

Islam is a set of spiritual principles.

Buddhism is the development of the mind.

Yoga concentrates on the attainment of pure consciousness.

But any of these mental concepts can harden into rigid rules which can be reinforced with rewards and punishments, heaven and hell,

This approach is not the true path however.

Both Jesus and the Buddha warned against rigidity in religion.

Because the true path is through the heart.

And the heart will make concessions according to love.
