“The Upanishads and the Gita are the true scriptures. Rama, Krishna , Buddha, Chaitanya, Kabir and so on are the true avatars; for they had their hearts broad as the sky and above all Ramakrishna” = When the quantum of negative decreases and the quantum of the positive increases human beings get evolved from demonic nature to ordinary human beings to great human beings and then to enlightened human beings to divine human beings. When the negatives become minimum or the level of nil , that human being will become an avatar. Thus swami Vivekananda said that the above mentioned are elevated souls known as avatars.
“It is in the books written by priests that madness like that of caste are to be found and not in books released from the God” = Ordinary human beings can classify human beings at lower level or higher level depending on their birth. But divine books will never point anyone lower or higher level. Thus Krishna dwaipaayana born to fisherwoman could become Veda vyasa and under take the mission of classifying the ultimate Hindu literature Vedas into Rg veda, yajur veda, saama veda and atharvana Veda based on the mantras meant for knowledge jnaana + karma + musically chantable + subject of ordinary human beings, respectively. Our Upanishads say Aham brahmaasmi and thathwamasi. I and you are the manifestation and manipulation of the divine power
“Work, work work- I care for nothing else. Work work work even unto death” = this is what we have to practise and preach. Every Indian should focus on karma yoga. The third chapter of bhagavath geetha says so. Go on working and working till the last breath.
“It is the heart, that conquers, not the brain” = The heart is the embodiment of love, affection, sympathy and the store house of all good qualities of human beings. Thus we say heart should be good. It is symbol of hard work also.
