How To Experience The Spiritual World - Here and Now

The light of one candle being communicated to other candles, although it burns separately in them,is the same in its quality. I adore the primeval Lord Govinda who exhibits Himself equally in the same mobile manner in His various manifestations."
Brahma Samita, verses 12,19
Life Is A Festival

The lecture below, given by His Divine Grace AC Bhativedanta Swami Prabhupada, explains this verse fully, including how to experience the energy of spiritual world in daily life. Amazingly, the whole process for spiritual liberation and joy is made clear in the following discourse.

evaṁ yo vetti tattvataḥ
tyaktvā dehaṁ punar janma
naiti mām eti kaunteya
[Bg. 4.9]
"Kṛṣṇa is explaining how one can very easily enter into the spiritual world, or the kingdom of God. The simple formula is that anyone who understands the appearance, disappearance, activities of the Lord as divyam, transcendental, with perfect knowledge of the Absolute Truth, simply by this understanding one can immediately enter into the spiritual kingdom.
To know the Absolute Truth is not possible by our present senses. That is also another fact. Because at the present moment we have got materially..., materially affected; not material senses. Our sense are originally spiritual, but it is covered by material contamination. Therefore the process is to purify, to purify the coverings of our material existence. And that is also recommended—simply by service attitude. Sevonmukhe hi jihvādau svayam eva sphuraty adaḥ [Brs. 1.2.234].
[No one can understand the transcendental nature of the name, form, quality and pastimes of Śrī Kṛṣṇa through his materially contaminated senses. Only when one becomes spiritually saturated by transcendental service to the Lord are the transcendental name, form, quality and pastimes of the Lord revealed to him.]The whole thing depends on our surrendering process and engage ourself in the service of the Lord. Then gradually, the Lord reveals to the devotee. That is the process.
So what is the birth of the Lord? There is no question of birth of the Lord or of the living entities. This subject matter we have already discussed in the last meeting, that the Lord and the living entities, both are eternal. There is no question of birth and death.
The same example, just like the sun: sun setting and sun rising.
Sunset and sunrise, it is simply adjustment of our own position. Actually, there is no sunset, there is no sunrise. The same example is applicable to our appearance and disappearance, as well as God's appearance and disappearance. We are eternal. We are eternally existing, but appearance means this body, appearance of this body. More
