Most of the saints and sages of the past are mostly social reformers, thus they are more concerned to the humanism rather than the truth. Their contribution is very valuable to live in the practical world. Thus humanism is part and parcel of the universe, which is mere illusion.
People think love is the means to self-realization but they are unaware of the fact that, love and hate are made of the same stuff. Love is not the means of self –realization. Love is very much necessary in practical life within the practical world. Love implies duality. Whatever is of duality is falsehood. Thus love is reality within the falsehood. Lover and love ceases to exist in reality because the experience of duality is not reality. The experience of practical life within practical world is reality within the waking experience but waking experience itself is mere illusion created out of consciousness. Thus lover and love are one in essence. Thus path of love is religious path because religion is path of individuality or duality.
In reality love and lover are one in essence. That essence is consciousness. The consciousness or soul is the innermost self. The innermost self is God. Call it Self, God, Christ, Brahman, inner Buddha or Emptiness or Nothingness or Sprit or Love it is all the same.
When one becomes aware of the ultimate truth as a person of the world he sees that the self or God [consciousness] pervades in everything everywhere in all the three states. Thus it is necessary realize the innermost self or God or Buddha or Christ, is the lover and love together.
Thus our conditioned love conditioned by physicality will not be able to recognize unconditional love the innermost self.
The love within the physical existence (practical world) is very valuable in practical life. Great master Paramahanasa Yogananad and many other sages in the past prescribed unconditional love to the humanity. And unconditional love is very valuable tool for the humanity which is immersed in practical life and practical world. We have to respect every sage for their service contribution to the humankind.
The path of love, path of humanity are limited to the practical life within the practical world. Path of love and path of humanity are the best tool to serve the human kind within the practical life with in the practical world.
Gnani loves humanity in the practical world but inwardly he is fully aware of the truth that the practical life within the practical world is mere illusion from ultimate standpoint.
Thus path of love should not be mixed with path of wisdom because the path of love is based on the duality and path of wisdom is based on nonduality.
The humanism is limited to practical life within the practical world. The path of love is path for humanity therefore, it is individualized path. Thus the path of love is limited to the physical structure, it cannot transport one to ultimate end. Thus seeker has to understand the fact that the practical life and practical world are part of the mirage from the ultimate standpoint.
