Bhagavad Gita entails the best definition of love that could ever exist. As per Lord Krishna in Bhagavad Gita pure love was above all sensuality, wantingness, craving, expectations. Pure love is above all earthly attachments, inhibitions of any kind.
Pure love as in Bhagavad Gita existed between Lord Krishna and Radha. Pure love exists between a true spiritual master (guru) and a dedicated Shishya (pupil). Pure love existed between Sri Ramakrishna Paramhansa and his favourite Shishya Swami Vivekananda.
Pure love existed between Sage Yajnavalkya and his second dutiful wife Maitreyi who not only believed in accomplishments of Sage Yajnavalkya but went after him, his philosophy to gain Brahma jnana in her lifetime. Sage Yajnavalkya is the composer and compiler of most voluminous Brihadaranyaka Upanishad.
Pure love is not what people carried in present times. There is a story in Hindi literature titled “Usne kaha tha”. This story is about pure love expressed by a perfect human being in a lady. It so happens that this gentleman loved this woman passionately with total pure intentions but never gets to marry her. The woman marries another man and her husband who is in the Army goes to the border to fight the enemy.
The woman fears for the life of her husband. She comes to know that one who loves her badly was a subordinate to our husband in the Army. She approaches this person, the perfect gentleman to save the life of her husband in times of need. And the inevitable happens. To save the life of our husband, the gentleman succumbs to death.
This is what pure love is all about, sacrificing life of self for sake of others. Intelligent parents in present times devote all their life for the betterment of their children. It is true love that is expressed in Hindi movie “Baghban”, something worth seeing many times. Anyone with no knowledge of Hindi can understand the gist of movie Baghban, an excellent picturisation of true pure love that could ever be practiced by mankind.
Pure love was never demanding nor were there any expectations in entire life ever.
