Only the human spirit is capable of being filled with God alone. Hence nothing worldly or of lower spirituality will ever truly satisfy us. That is just ego-spirituality and does not bring anyone closer to Enlightenment. You should set your goal on Enlightenment and in the name of God and THE SELF/IT shun every other kind of “spirituality”. There is one way to God and one way only. It is said there are many, and in a sense, for the preparatory stages, that is true, but ultimately there is only one. That one path, having been described throughout Jan’s books , is an attempt to convey that one path.
Let it be reminded that the Peace known by lovers of God comes from their heart being fixed, in longing and thought, in the Love of God. It is a Love-Bliss that sings and finds peace and burns with a hot fire and contemplates the super-essential Void of The Mother and The Holy Spirit and the Supreme Being: the Avatar, Son or Daughter of God. Only people who really know this from being IT know true Peace.
The in-itself eternally resting pure unmanifest Being, which is the One and out of which you are an individuality.
The primal energy in man. The energy which individuated you as you and which will grant you liberation.
The Grace that guides Kundalini on its path of unfoldment and of uniting itself, and you, with the Absolute Self.
LOVE. Everybody knows love to some degree. Love for one’s wife and children for example. Or love for one’s teacher. Or love of religious icons and art. Feel this love as often and as strongly as possible during the day, then let go of the object of the love and just feel the love in and as itself. Stay with it for as long as possible. Enhance it with your breath (this technique cannot be explained, but you will figure it out with a little experimentation). Merge your conscious awareness with this love and you will feel the love naturally flows towards the Divine, to God.
DEVOTION. As love grows in you, and you connect with God, you will feel devotion to God. It is unavoidable. You cannot have real devotion without real Love, and the deeper and stronger the Love, the better. Thus real Devotion develops after real Love develops. You long for God with all your heart. You will cry tears of Devotion. In days or period when you do not feel that Love/Devotion, your heart aches with longing. Your lover has gone; you know not where. Will he/she come back? I assure you, God never abandons a true Lover and will come back, He/She is merely testing you. So remain Devoted. If not you may fall into apathy and boredom and get dragged down into sloth. If you find the joy of meditation and prayer has deserted you, still pray to God to take you out of that darkness you are in. Read holy books for inspiration.
SURRENDER. It can be said to be a higher octave of Love, similarily Surrender can be said to be a higher octave of Devotion. When Love-Devotion is strong you let go of everything and merge with IT, that is Mystical Surrender. And I mean “everything”. You let go of your sense of being a unique individual, yourself. You let go of desires, attachments, aversions and so on. Eventually you transcend the I-ness and merge into Pure Being, the SELF/IT. You surrender to GOD/IT/THE SELF beyond the super-essential clouds of first unknowing then non-knowing.
Once you have perfected Love, Devotion and Surrender, you have fully renounced the world. You are in the world, but not of it. You still enjoy things of the world but you love God in and as the thing, not the thing as a separate sensual phenomenon. This is True Renunciation, not self-denial and suppression of healthy, normal joys in life. You could say God has taken charge of you, but it is in a happy Surrender to God. Once Love of God has taken full control of your emotions and your very Being, then Love of the world-as-such fades away.
