Prophet MuhammadThe truth does not necessarily come from priests, or from the superstitions of whole peoples. It come from Allah, and where there is direct revelation, there is no room for doubt." Abdullah Yusuf Ali, The Holy Qur'an
Was the Miraj as a physical or spiritual journey?
In order for us to have a reasonable understanding of Islam and Allah, it is important for us to have the right concept. Without the right or true concept of something or someone, it will be difficult for us to comprehend the true nature of that thing or person.
"In the case of Miraj, putting aside logic and man-coined conclusions, let us refer to those close to our Holy Prophet and see what they have reported in support to the spiritual concept of the Miraj.
It is on record that one of the closest person to the Holy Prophet was Bibi Aisha, and she held the belief that the Holy Prophet's experience of Miraj was in a vision, and not physical. (c.f. Tabari, Zamakshari and Ibn Kathir in their commentaries on 17:1). The actual phrase used that "he was transported only in spirit (bi ruhihi) while his body did not leave its place." ...
Again it is written, "And he awoke and he was in the sacred mosque" (B:98:37). In another of Bukhari's Hadith, it is written, "whilst I was in a state between that of one sleeping and one awake" (Bukhari 59:6).
These are just some of the authentic records which shows clearly that the Miraj was a spiritual experience of the Holy Prophet, and was not a physical one.
If for argument sake, we interpret the Miraj as a physical journey of the Holy Prophet, let us examine some of the ramifications of such a notion.
First and foremost, it will signal us that the Holy Prophet Muhammad was much more than a normal mortal being, something which he emphatically denied time and again. Many times he was questioned by his opponents that he was a true prophet of God, if so, then perform certain miracles and they would believe in him. His only reply was "I am an ordinary mortal just like yourself."
Secondly, mounting a physical Buraq and riding to the Heavens would defy the laws of nature. Holy Quran says, "there is no incongruity in the nature made by Allah".
Thirdly, nothing physical can enter a spiritual domain. A physical Holy Prophet, together with a physical Buraq, cannot enter a spiritual abode such as the Heavens. (Holy Quran) 
Keeping in mind the last sentence that "a physical Holy Prophet, together with a physical Buraq, cannot enter a spiritual abode such as the Heavens", the Id-Adha of 1994 is explained.
Eid Al-Adha Of 1994
On that holy day of Id-Adha 1994 Kash was told to send greetings to Prophet Mohammed. This day is celebrated by Muslims worldwide to mark the culmination of the pilgrimage to Mecca, and is one of the holiest in the Islamic calendar.
Kash sat in meditation and immediately surfaced through the celestial clouds, his meditating self momentarily suspended in midair. Slowly he floated down and merged into his spirit-body.
The Clear White Light shone ever so brilliantly from behind the Eternal Throne as Al-Muntazar (The Hidden Imam Mahdi) sat in Bliss and Joy. He greeted and told Her of his desire to see Prophet Muhammad.
She agreed and immediately levitated him a few inches above the soft bed of clouds that stretched infinitely in all directions. They then voyaged across the inner spiritual universe, just as Prophet Muhammad had done on the Buraq more than 14 centuries ago.
When they reached their destination the Ruh of Allah introduced Kash to Nabi Muhammad, the Messenger of Allah.
Prophet Muhammad was invisible but Kash could feel him through vibrations flowing from his hands, as if they were 'talking' to him. He knew exactly where Prophet Muhammad was sitting and what was His form, just as he had detected the invisible Shri Buddha.
Kash bowed down to the Prophet of God Almighty and conveyed greetings of Id Al-Adha in English. The Ruh of Allah Shri Mataji Nirmala Devi, who could see Prophet Muhammad, translated Kashs greetings into Arabic.
Prophet Muhammad returned the greetings in Arabic. Shri Mataji then translated the greetings into English, and replied that Prophet Muhammad also thanked him for sending the Id-Adha greetings. The three of them then raised their Kundalinis and meditated together.
When it was over Kash again bowed to Rasul Allah and paid his respects. He then left with Al-Muddaththir (The Enfolded) back to the Land of Al Nur where he asked permission for departure.
As he closed his spiritual eyes he began descending through the heavenly clouds, returning to this blind world of scriptural distortion and religious fundamentalism.
Note: The Prophet once journeyed on the Buraq within his own being, a mystery revered by Muslims as Mi'raj (The Night Journey). There is evidence that Prophet Muhammad never left his room when He experienced this journey, and His wife bears witness that at all times He was lying beside her.
"Now, it is agreed by all that Muhammad's Ascension was a matter of seconds or minutes instead of being days, months or years, and the words used for it by all biographers is Miraj, the same as used by God for the ascension of the angels or spirits who have no bodies." 
Prophet Muhammad did travel towards Heaven and met the prophets on the way since all these mystical journeys took place within Himself! Even the Buraq was a mystical animal of the Spirit World, not a physical beast found on Earth. This extraordinary metaphysical Truth is known as Al Isra' (The Night Journey) surah 17:1:
Glory to (Allah) who did take His Servant for a Journey by night, from the Sacred Mosque to the Farthest Mosque,
Whose precincts We did bless in order that We might show him some of Our Signs:
For He is the One Who heareth and seeth (all things).
Schuon has attempted to capture the mystery of the Qur'an in these words: "In order to understand the full scope of the Quran we must take three things into consideration: its doctrinal content, which we find made explicit in the great canonical treatises of Islam such as those of Abu Hanifah and Et-Tahawi; its narrative content, which depicts all the vicissitudes of the soul; and its divine magic or its mysterious and in a sense miraculous power; these sources of metaphysical and eschatological wisdom, of mystical psychology and theurgic power lie hidden under a veil of breathless utterances, often clashing in shock, of crystalline and fiery images, but also of passages majestic in rhythm, woven of every fibre of the human condition."
