In reality, there is no other consciousness except Krishna consciousness, spiritual consciousness. Thus, even during our stay in the material universe, we only need to intensify our Krishna consciousness to immediately live in the spiritual world.

For example, living in a temple is tantamount to living in the spiritual realm, due to the constant service we offer to Krishna. Many activities are performed there for Krishna. Therefore, all those who strictly adhere to the principles of Krishna consciousness truly live in the spiritual world, not in the material universe, even if they are still there. Their space is no longer material but now spiritual.

Such is the power of Krishna consciousness.

How can we achieve true eternal happiness?

If we want to experience true happiness, we must absolutely return to God. It is an absolute necessity.

True happiness does not exist in the material universe, hence the imperative need to return to God, to our original home, located in His eternal and absolute kingdom.

The Lord desires that each of its integral parts return to the divine kingdom, to enjoy an eternal existence of total bliss. This is the true meaning of the creation of the material world.

In truth, the purpose of our existence in this material world is to enable us to experience the imperative need to return to God, and to understand that true, permanent happiness does not exist in the material universe. Wherever we go in the material cosmos, regardless of the planets that make up the countless galaxies, we will find true happiness nowhere.

It is only with Krishna, the Supreme Personality of Godhead, that we will find true, perfect, total, and permanent happiness, for the Lord is its original source and divine bestower.

The intelligent person must be mindful of the imperative need to return to God, to his original abode, and must absolutely guard against ever forming futile, illusory projects and seeking happiness in a place where it is only an illusion, a myth.

The three attributes and modes of influence of material nature—virtue, passion, and ignorance—manifest themselves as matter, knowledge, and action, and impose on the being of eternally spiritual nature conditions of cause and effect, making them responsible for their actions in matter.

It is in the kingdom of God that true life, true sublime, incessant, and eternal happiness, is found.

The spiritual world is the real abode of the spiritual beings that each of us is.
