What is Sadhana ?

-the purification of the nature,
- the consecration of the being,
- the opening of the psychic and the inner mind and vital,
- the contact and presence of the Divine,
- the realisation of the Divine in all things,
- surrender,
- devotion,
- the widening of the consciousness into the cosmic Consciousness,
- the Self one in all,
- the psychic and the spiritual transformation of the nature.
If these things are neglected , then that is not Sadhana.
