The Incarnation of  
Jesus Christ On Earth...

As Explained by 
Kriyayoga Master and Scientist,
Guruji Swami Shree Yogi Satyam

Jesus Christ - The Great Incarnation and Master of Resurrection, 
resurrected as a prophet on this earth to show the existence of  immortality. 
He repeatedly taught that there is no death.

Jesus stated that I was existing before in God in a different form. 
I am existing now in this form. I perceive each moment that I and God are one... 
The following quotes from The Bible establish this:

"Before Abraham was, I am."  John 8:58

"I and my Father are One..."  - John 10:30

Jesus came on earth to demonstrate resurrection to mankind and for this Jesus gave Himself to Crucifixion. Jesus (the good shepherd), led all those who followed his teachings (the sheep) towards the Realization (Truth) that we are One. 
Jesus proclaimed, as given in The Bible
:  

"I am the good shepherd: the good shepherd giveth his life for the sheep"  
-
  John 10:11
"I am the good shepherd, and know my [sheep], and am known of mine. 
As the Father knoweth me, even so know I the Father: 
and I lay down my life for the sheep. 
And other sheep I have, which are not of this fold: 
them also I must bring, and they shall hear my voice; 
and there shall be one fold, [and] one shepherd. 
Therefore doth my Father love me, 
because I lay down my life, that I might take it again. 
No man taketh it from me, but I lay it down of myself. 
I have power to lay it down, and I have power to take it again. 
This commandment have I received of my Father." 
- John 10:14-18

Just like Jesus, Realized Master Lahiri Mahasaya (1828-1895) from Banaras, U.P., India, resurrected many times and appeared to several of his disciples.  Swami Shree Yukeshwar Giri (1855 - 1936) , the great and close disciple of  Lahiri Mahasaya, has also demonstrated the same truth of resurrection. He appeared physically one week after his great Mahasamadhi ( final departure ) and re-appeared three months later at Regent Hotel, Bombay, before his beloved disciple, Paramhansa Yogananda, to explain about the astral world.  In 1981, Shree Yukteshwarji appeared once again at 22 Woodstreet in Calcutta .

These demonstrations of resurrection by Jesus Christ and all other  
Realized Masters serve to show humanity that our true nature is Eternal. 
These Masters practised a pure scientific technique - Kriyayoga, 
which is but The Science of Resurrection. 
And Kriyayoga was practised by all Saints and Sages and 
Prophets of all lands and ages. 

The Spiritual Science of Kriyayoga is for all mankind to live life while perceiving our true nature - Omnipresent, Omniscient, Omnipotent Spirit (Truth). In doing so, we realize Infinite potential within. Each of us should practice Kriyayoga sincerely to experience Truth and fulfill the purpose of the lives of all Masters, Prophets, Saints & Sages.
