If Hinduism has survived the onslaught of barbaric Islamic invaders for 600 years followed by British invasion by 200 years, Hinduism has nothing to lose.
Hinduism is the main Dharma (Sanatana Dharma) from which flowed, all smaller tributaries like Jainism, Buddhism, Christianity and Islamic Dharma. The preceptors of all right from Mahavira, Gautama Buddha and Jesus Christ and Prophet Mohammed indulged in teachings of Bhagavad Gita, Upanishads even Vedas to reach state of enlightenment.
In the entire a spiritual world there was nothing more pure than teachings of spirituality contained in Bhagavad Gita. One single scripture Bhagavad Gita sufficed for entire humanity to reach state of enlightenment.
Indian spirituality is part of Hinduism Dharma, Hinduism religion that is not only the oldest, but the best and shall also continue to do so. If a person world over could gain enlightenment, it was only possible through teachings of Bhagavad Gita.
No religion or its followers in entire world was competent to scuttle development of Hinduism.
Hinduism existed since mankind came into being. Before naming it Hinduism it was termed Sanatana Dharma, Sanatana meaning eternal. Hinduism shall also continue to exist until the end times when mother earth gives way with the death of sun. By that time all living beings on mother earth would have reached state of enlightenment. We still have few more billion years to go.
The question of Hinduism becoming extinct can be a slogan for the limited few provoked by fascist, radical tendencies in vogue.
By and large Hindus were peaceful, did not retaliate even facing enemy head-on, prime reason why they suffered at the hands of Islamic invaders and the British. With coming of Kalki Avatar this practice of cowardice will change.
In the name of ahimsa (non-violence) practiced by Mahatma Gandhi if Lala Lajpat Rai succumbed to British lathies then Mahatma Gandhi is squarely to blame for his untimely death. God would never forgive Mahatma Gandhi for this suicidal act of his. Millions of peaceful Indians died only due to Mahatma Gandhi’s practice of ahimsa (so-called non-violence). Had Sardar Patel been the first prime minister, India would have been superpower number one now.
Still, India has not lost its spiritual glow. India shall again rise from the ashes.
In few more years mankind would witness advent of Kalki Avatar, a one-man army one possessing powers almost equaling Lord Krishna. This ruthless crusader of truth and only truth will finally succeed in establishing Dharma (righteousness) against evil forces of adharma (lawlessness). The dawn of Satyuga (the awaited golden period) would occur with coming of Kalki Avatar. During that time India would convert itself to greater India with a population exceeding 1600 million.
The strength of India is spiritual something that does not diminish with time. Such is the power of an enlightened one that if all sacred texts in the entire world get burnt, the enlightened one having capability of an avatar would reproduce them again. An avatar is a person who is directly connected to God, Brahman in Hinduism the creator of entire cosmos.
The survival of Hinduism is not at stake, rather it is vice versa. Humanity survives because Hinduism exists. In absence of spiritual teachings of Hinduism life on mother earth could not exist for long. Prime reason why God ordained advent of an enlightened one every 100 to 200 years! In the last about 150 years amongst 7 billion people existing world over Sri Ramakrishna Paramhansa and Maharshi Ramana finally succeeded in reaching God in their lifetime.
Furthermore if we minutely observe world over, Hinduism is gaining strength day by day.
The deficiency in the working of Vatican is also being viewed badly world over. The Islamic world seems governed by terrorist forces.
In the circumstances the only respite to the world is from Hinduism religion time will prove this again and again.
