Did Jesus have to undergo any kind of esoteric training, as Milarepa did centuries later, in order to recover his light being capabilities?

Jesus Christ had our backing. He had to prepare himself, as we have explained, to be ready to accept this mantle of divine capability, knowing that he would be making himself a target and taking on great risk for those times, in setting himself up seemingly above others, and claiming a loftier purpose and pedigree, and challenging the powers that be and their authority to rule over others arbitrarily and with a heavy hand, as was happening when he came into being. So this was not something akin to becoming a rock star, it was truly becoming a warrior for the light in a setting where humanity was in a contest with invading interlopers running the world and controlling humans quite savagely through a series of constraints and outright punishments. It was an act of great courage to take on the role of messiah. And to do so with the gentleness and love Jesus Christ bestowed on everyone he met, was a singular combination of soul attributes that made him an outstanding divine representative and example for the ultimate in balancing needs and opportunities to be effective in life, and effective in dealing with others no matter what the circumstances or issue at hand. When love is available and can be dispensed, any problem can be met with and solved. This he demonstrated over and over again with his healing work and was the most important of his messages for humanity, that a person’s lot in life and their suffering need not be seen as inevitable and endured with a fatalistic perspective that one might simply be doomed, but rather that divine grace can make up for personal shortcomings and allow a person to break free of their difficulties and transcend them by virtue of belief in the divine and wanting to have divine love in their life.
