Yes, this is absolutely true as far as all earthly life is concerned.
Upon Earth, all life is knowingly or unknowingly striving towards Perfection through the process of evolution. It is inbuilt in earthly creations. We are as if pre-programmed to evolve and hence the general dissatisfaction that haunts all creatures here. This is because of the presence of the psychic principle that is found exclusively upon earth.
It is however, more difficult to say that this is true of the universe. There are many typal worlds and universes where there is no progress or evolution. These are the typal worlds, fixed to their types. And hence there is no striving for anything higher or greater. So the word yoga applies mainly to all earthly life. And it is so mainly because of the presence of the psychic principle. It is the presence of the psychic being, whether overtly or covertly, that pushes creation towards yoga.
Yet, since all creation is interconnected so human beings engaging in conscious Yoga is invariably going to impact the rest of the creation, including the typal worlds and their creatures. In this sense, all creation engages in Yoga, directly or indirectly, consciously or unconsciously. But the main event, the Yoga, is going on upon earth.
Affectionately,
