Serve. Anything that's useful, use it; if not, then let it go. God and the devottee are like a tree and its branches, and the 'calling' of the branches, is to serve the tree. What does the tree need? what does God need?
The devotee comes here to glorify, adore, or if you like, manifest the Will of God. The happiness of the tree lies in being served by the branches, the leaves, petals, as they reach out to humanity.
We came here to Love God; to serve Him through Creation. It is impossible to do this without Love. Here I speak of the 'Higher calling' as there are many who are called by God for a different purpose, or to serve in a different way. All comes from God. There is nothing outside the divine.
Where do you start? Nothing is wrong with scriptures and they all have the same basic rules: Prayer, both verbal and silent; meditation; selfless service to mankind; Gratitude; forgiveness ...
Make a shrine at home. A table, white cloth, incense, a candle and a picture of your favourite godly teacher. Christ, Buddha, Krishna or simply use the flame of a candle to meditate. It may help if you read a little, breathe gently a little, play devotional music ... talk to God.
Prayer is an invocation of the Higher Energy. When you fall silent, that is to say, when the mind is calm, quiet and vacant, you will feel a very powerful inner energy of Peace of Love. Do not force it; do not push or pull, but surrender.
To return to the shrine. You need to sit on a chair with your eyes and shoulders relaxed and look at the flame of the candle. Keep your back straight as the spiritual energy travels up the spine.Do this religiously day after day for three months in 15 minute sessions morning and evening. This will harness your energy and make you more one-pointed and receptive to the Higher Light.
Love, service, goodness and a burning inner cry are necessary. You must not only love but long for what you seek. Find a good teacher, or if you like what I say, then keep writing to me.
The Higher way is not one of witchcraft, the loving and safest way is the way of the Heart. Walk the narrow Path and never look at the beautiful flowers that it will inevitably offer, as you will stumble or fall. Keep going, practice loving kindness; compassion, serve others. You will stumble, but with daily and incessant spiritual practice, you will improve.
Finally, remember that the 'enemy', if there be one, is always within not outside: Lust, greed, ego, anger, attachments...
