The methods of annihilation as are invented by the human brain such as the atomic bombs etc are also Her creations but the deluded Ashuras, who are caused to act by the modes of Prakriti the material nature, do think themselves as the originator or inventor of such weapons. In that way a constant struggle is going on between the asuras and the prakrti and the asuras are thus being punished in different ways which the asuras cannot overcome by any method except by full surrender unto the Almighty God.
In the Bhagwat Geeta the last instruction is to surrender fully unto Him the author of the Bhagwat Geeta but unfortunate men of demonic mentality misunderstood the teachings of Bhagwat Geeta as a method of sophistry and therefore the same Personality of Godhead Sree Krishna in the garb of a transcendental devotee preach the same techniques of Bhagwat Geeta i.e. full surrender unto the Almighty God or His different potencies in a demonstrative way.
The method of His demonstration was also very suitable. He inaugurated the Sankirtan movement accompanied with melodious song which method has been found practically very effective amongst the masses. It is not possible for the masses to study the Vedanta or to undergo the difficult mystic processes especially in the Kali-yuga when the general people is indolent, unfortunate, shortlived and always disturbed by physical and mental tribulations. So they the general mass of people are fallen in the estimation of the great saints and as such for them Sree Chaitanya Mahaprabhu is the only hope for deliverance. When Sree Chaitanya Mahaprabhu visited Baranasi He was invited to a philosophical discourse by the Prakashananda Saraswati a great giant scholar and Sanyasi of the Mayavadi or Shankar Sampradaya and discussion was made on the Vedanta philosophy. Shree Chaitanya Mahaprabhu was victorious in that discussion and converted the great Sanyasi with his 60,000 followers to His cult of devotion and established His easy method of Samkirtan movement the most suitable method for the deliverance of the people in general.
So on the occasion of the Lord's 463rd advent day, I beg to suggest that in the Gurumandal some such preaching method as was adopted by Lord Chaitanya, may also be adopted for the benefit of the general people. The upashana of yoga system as recommended by Shastriji may not be suitable for the people in general because hardly they will be able to adhere to the principles of yoga and it may be as suggested by the Rajguru Shastriji that in the default of such yogic method the performer may fall ill and thus become doomed for his life.
