1. Becoming One with God

World Scripture

Do you not believe that I am in the Father and the Father in me?
John 14.10

Heaven and earth contain me not, but the heart of my faithful servant contains me.
Hadith of Suhrawardi (Islam)

Abide in me, and I in you. As the branch cannot bear fruit by itself, unless it abides in the vine, neither can you, unless you abide in me. I am the vine, you are the branches. He who abides in me, and I in him, he it is that bears much fruit, for apart from me you can do nothing.
John 15.4-5

As rivers flow into the sea and in so doing lose name and form, so even the wise man, freed from name and form, attains the Supreme Being, the Self-luminous, the Infinite. He who knows Brahman becomes Brahman.
Mundaka Upanishad 3.2.8-9 (Hinduism)

Meditate upon Him and transcend physical consciousness. Thus will you reach union with the Lord of the universe. Thus will you become identified with Him who is One without a second. In Him all your desires will find fulfillment. The truth is that you are always united with the Lord. But you must know this.
Svetasvatara Upanishad 1.11-12 (Hinduism)

And we all, with unveiled face, beholding the glory of the Lord, are being changed into His likeness from one degree of glory to another; for this comes from the Lord who is the Spirit.
2 Corinthians 3.18

Bright but hidden, the Self dwells in the heart.²³ Everything that moves, breathes, opens, and closes Lives in the Self. He is the source of love And may be known through love but not through thought. He is the goal of life. Attain this goal!
Mundaka Upanishad 2.2.1 (Hinduism)

Every Buddha Tathagata is one whose body is the Principle of Nature (Dharmadhatu-kaya), so that he may enter into the mind of any being. Consequently, when you have perceived Buddha, it is indeed that mind of yours that possesses those thirty-two signs of perfection and eighty minor marks of excellence [which you see in Buddha]. In fine, it is your mind that becomes Buddha, nay, it is your mind that is indeed Buddha.
Meditation on Buddha Amitayus 17 (Buddhism)

In spontaneous joy is rising the mystic melody; In the holy Word my heart feels joy and perpetually disports. In the cave of spontaneous realization is it in trance, Stationed on a splendid high cushion. After wandering to my home [true self] have I returned, And all of my desires have obtained. Devotees of God! completely fulfilled is my self, As the Master has granted a vision of the Supreme Being, Realized by mystic illumination. Himself is He King, Himself the multitude; Himself the supremely liberated, Himself of joys the Relisher; With Him seated on the throne of eternal justice, Ended is all wailing and crying. As I have seen, such vision of Him have I conveyed— Only those who are initiated into this mystery have its joy. As light is merged into Divine Light, has joy come: Nanak, servant of God, has beheld the sole, all-pervading Supreme Being.
Adi Granth, Majh, M.5, p. 97 (Sikhism)

God is huge, but a human being is a microcosm of the cosmos. By penetrating into God, we can experience God within us. When we experience this, we can say, with Jesus, “I am in the Father, and the Father in me.” (John 14.10) Although God is infinitely large, He can do His work only when human beings fully dwell within Him.

When your mind and body are united as one, you will be in your eternal dwelling place, the center where God abides. Then you can possess even God. This state arises when true love is restored; it is the supreme goal of human beings who had lost everything as the result of the Fall.
(294:98-99, June 14, 1998)

The path of religion is to stop living as animalistic human beings and become humane human beings. Eventually we are to become divine human beings. We are to participate in the divine realm. We are to become people with a divine nature who practice divine love and rejoice ever more in eternal happiness.
(117:37, January 31, 1982)

Love is the central point, the rope that binds God and human beings together eternally. When embodied human beings attain oneness with God, their heart is immersed in a state of profound awareness and their emotions thrill with boundless happiness. Through love, God and human beings become one. Through love, human beings and the world become one. Here is the starting point for the realization of the ideal world that fulfills God’s purpose of creation.
(35:356, October 13, 1970)

When you are united with God in true love, you can have dominion over all God’s creation, both physical and spiritual. When you live completely for others, you are reaching the very essence of God. Then, God’s will becomes your will, and God’s feelings naturally come into your heart. Living this way, you become a resonant vessel of God’s heart and love. You and God will always resonate together, like two tuning forks.
(201:206, April 9, 1990)

As existent beings in front of Thee, we entrust to Thee our whole selves: We shall be Thy branches and leaves. When Thou art sorrowful, we shall also be sorrowful; when Thou art happy, we shall also be happy; when Thou dost hurry to work, we shall also hurry to work. Permit us to become Thy sons and daughters who stand beside Thee, as Thou dost deal with every aspect of our world.
(42:59, February 21, 1971)
