There is a Law that has been woven into the fabric of this Universe, which decrees that everything that has a beginning must have an end, and that end must be joined to the beginning. This is the Cycle of Karma which manifests in millions of different ways here on Earth, but always according to that precise logical consistency of The Law that has been woven into this Universe.
According to this Law, those who have been sent out on spiritual missions to Earth are required to fulfill these spiritual missions completely. If for some reason a person who is sent out on such a spiritual mission does not fulfill this mission, if on account of some circumstance he chooses a different path from the one originally ordained for him, then the one sent on this mission has deviated from the spiritual mission he was given, and thus his spiritual mission remains incomplete.
One may object that it is not possible for a person who has come on a spiritual mission to fail in that mission. Indeed, that is how it should be! How is it possible for someone who has been blessed with great Spiritual Knowledge to deviate from the path that he has to follow on Earth?
And yet, not only is such a thing possible, but it also happens manifold! You may be surprised to know that in the late nineteenth/early twentieth century, a multitude of such blessed ones were sent to Earth to lay the foundation for the spiritual transformation of the world. This multitude, spread out all over the globe, comprised of numerous blessed individuals, each with different talents and abilities, but all filled with Spiritual Knowledge and Illumination from Above. They were all sent to Earth during this very precise time of the early twentieth century to build a foundation that would uplift Earth from out of the old wrong ways of living into the new!
They were the messengers of the Aquarian Age, whose activity should have converged upon a single point, rather than diverged! Had these individual messengers of Truth found the way to each other at that time, had they worked together in a single, concerted effort the world today would not be what it is today.
These individuals were the spiritual leaders of many nations, including India! They were also spiritual leaders in great temples, churches, mosques, and also leaders who formed their own spiritual movements in different parts of the world, who eventually came to be known as messiahs. Their goal was not to lead people to earthly independence, but rather to institute the practices that would revolutionise the human race and lead to true Peace on Earth. That was their task at that time!
But instead of working to converge, many of them developed their own ideas. Because, after incarnating on the Earth, they were also under the influence of the over-developed intellect, which is bound to space and time. This intellect, with its own bound will and so-called "free thinking", was able to drown out the voice of the spirit. Consequently, a convergence of the activity of these blessed ones did not take place. Different movements arose which all went in different directions. Today you find the movements or religions started by many of these individuals, but none of them are really working together for the spiritual upliftment of the human race.
Some decided only to lead their people to earthly independence and focused on this. Others desired spiritual independence, but gave in only to the purely materialistic needs of the people. Still others felt themselves specially called and started religions of their own, eventually calling themselves messiahs or christs. Yet others gravitated to the material possessions that came to them and sank into exclusively building up materialistic and power-mongering way. And there were also those who focused solely on science, who made some great discoveries during this time, but then forgot about God and His Laws. In short, they all forgot their real task on the Earth.
Generally speaking, these messengers of the Aquarian Age thus failed in their tasks and were diverted by intellect, instead of finding a point of convergence in their activities. As a result of this, they too have burdened themselves with a Karma that can only be redeemed here on Earth. They are thus required to return to the Earth by The Law of Karma and pick up where they left off, if they come to recognition in time!
This time they all have it much harder than before, for they have to deal with the consequences of their failures, which they see all around them in the polluted and corrupt humanity of today, which only cares about money and power and has lost all sense of spiritual things, even in matters of religion. They also see the fruits of the spiritual or religious movements that they set up during their time and how corrupt these too, have become. Their task is much harder now and they feel more pain in their heart when they realise how wrong they had been to have ignored the path of convergence. Yet, this is all learning, experiencing and ultimately redemption for them! And also for those who now assist them in their task of redemption!
The Law of Karma, the Law of Reciprocal Action, of Sowing and Reaping, Immutable, unchangeable, adamantine. Neither you nor I can divert this Law by even a hair's breadth! It is steadfast and immovable, unshakeable! In this Law lie the answers to all the great questions of life, thus also why the great leaders of India, the originally Blessed Ones must return to experience their former failure!
