Christian faith does not make an ordinance to pray; prostration; sit; hands folded; raise their hands; stand; shout; whisper; crying and so on. No provision of clock and time as written in Ephesians 6:18.

And pray in the Spirit on all occasions with all kinds of prayers and requests. With this in mind, be alert and always keep on praying for all the Lord’s people. (Ephesians 6:18)

There is no provision to have to wear certain clothes when praying, no specific choreography to pray; Prayer is not just the pronunciation of mantras that are repeated; Strictly speaking there is no Shari’a binding on procedures-how to worship and prayer pronunciation. And the Lord Jesus has given examples. We also often do the prostrations of prayer as Jesus did, and it is allowed, but the Christian faith does not require always prostrate.

The definition of prayer is as follows: The relationship of fellowship with God in the name of the Lord Jesus Christ. Or rather Prayer is personal communication with God.
The underlying principle is the principle of holiness, not religious behavior.

For the eyes of the Lord are on the righteous
and his ears are attentive to their prayer,
but the face of the Lord is against those who do evil.
(1 Peter 3:12)

Prayer here is to emphasize the spiritual aspect of his physical open (ordinances pray). Praying is: to pray in spirit and truth, not the physical routines and procedures, nor the provisions of praying in a single day; not limited to space and time; do not have to wear certain clothing; We can always pray! this is the simplicity of the Gospel!

And when you stand praying, if you hold anything against anyone, forgive them, so that your Father in heaven may forgive you your sins.
(Mark 11:25)

The essence of praying is communication to the Lord, you could write an essay based on this fact. The origin of faith is believing and unconditional love.

Each religion approaches the divine in a unique way. Here are ten universal paths practiced by devotees to find God and connect with the higher self.

Every path to God is a personal experience, a private journey. No one path is inherently superior, as all paths to God are valid and useful.
Jesus said, “I and the Father are One.” (John 10:30) Humans and God are one. As devotees draw nearer and nearer to God, the ultimate goal is to merge with the Divine in an intimately spiritual union. Sri Ramana Maharishi, the famous Indian guru who achieved enlightenment at the age of 16, asserts, “God, Guru, and the Self are the same.” (p. 10, Erase the Ego)
Meditation as a Means to Draw Near to God
When a devotee quiets the mind, the inner voice can be more easily heard and heeded. Meditation allows for the cultivation of the state of mind needed to achieve enlightenment.
Buddhists, Christians, Hindus and other religions use meditation as a means to quiet the inner chatter and hear the voice of God, or the wisdom of the Higher Self.
Prayer as a Communication and Primary Path to God
Prayer can take many forms, including recitation of a mantra or repetitions with a rosary. Prayer can be a silent plea to the universe or a specific, intimate dialog with a personal, living God.
Prayer can involve specific requests of God or the Universe; expressions of appreciation for blessings; and communications of thanks, or cries for help.
Temporary Vow of Silence to Find the Higher Self and God
Silence does not just involve resting the vocal cords. Many religions advocate silent retreats, such as Christians, Hindus, and Buddhists.
Ritual silence can be used as a religious tool to quiet the mind to a deeper level than a meditative session. Silence is a disciplined, unique way to connect with the Higher Self and with God.
Yoga as a Discipline to Reconnect the Mind, Body, and Spirit With God
This ancient discipline is a subtle yet powerful path to God. The root word “yuj” means “to join, to yoke, to concentrate one’s attention.”
According to the Sanskrit Glossary of Yogic Terms, yoga is “a method of practice leading to conscious union of the human being (atman) with the universal existence of Brahman.” Brahman is the Hindu Trinity Godhead, similar to Christianity’s concept of the Holy Trinity. (Yoga Publications Trust, 2007)
Tithing and Offerings to God
Flowers, money, and personal sacrifice (as Catholics practice during Lent) are all examples of devotees’ external expressions of offering a part of themselves. Devotion is expressed through offerings, gift giving, giving of oneself. Tithing and offerings are expressions of love.
Acts of Kindness and Compassion as an Expression of the Divine
Jesus preached the importance of loving others, including it as one of the Ten Commandments given to Moses. The Dalai Lama teaches that compassion can be learned, and calls all who wish to achieve enlightenment to practice compassion.
Forgiveness is a supreme act of compassion, and also shows emotional and spiritual maturity. To forgive is divine, and is one way to draw closer to God.
Study of the Holy Texts Illuminate the Path to God
The Jewish religion emphasizes study as a means to understand and draw nearer to God. Christians study the Bible, revering the sacred text as a manifestation of God Himself: “And the Word became flesh…” (John 1:14)
Healthy Love of Self and Emotional Maturity as a Path to God
If God and the Self are the same, then a healthy love of self is absolutely necessary in spiritual growth, devotion to and love of God. Healthy love of oneself is a step in reconnecting to the Higher Self and emotional maturity allows for synthesis of mind, body and spirit.
Ethical Decisions Draw the Righteousness Near to God
Ethics does not involve right vs. wrong or good vs. evil, but rather entails a consistency of moral code. While some religions may differ on ideas and philosophies of morality, ethics and righteousness prove a powerful path to God, as a disciplined approach to what one believes is right.
Rituals as an Outward Expression of Devotion and Commitment to God
Pagans, Christians, Jews, Muslims, Hindus, Buddhists and others all practice religious rituals. Culturally, humans crave ritual to give order and increase meaning to outward acts of devotion. Rituals can provide structure and discipline to devotion. Some use rituals as a tangible lifeline that leads directly to God.
Devotees can use one, several, or all of these paths to God and to the Higher Self. For example, japa mala combines ritual with prayer and meditation.
Just as seekers approach the study of the Kabbalah, Jewish mysticism, from different angles, so the seeker can approach and ultimately unite with the Divine, the One God, the Higher Self, or the Universe using any of these valid and powerful paths.
