“Whatever we see in this world is simply an expansion of different energies of the Supreme Personality of Godhead, who is exactly like a fire which spreads illumination for a long distance although it is situated in one place.” This is a very vivid example. Similarly, it is stated that just as everything in the material world exists in the sunshine, which is the energy of the sun, so everything exists on the basis of the spiritual and material energies of the Supreme Personality of Godhead. Thus although Kṛṣṇa is situated in His own abode ( goloka eva nivasaty akhilātma-bhūto ) where He enjoys His transcendental pastimes with the cowherd boys and  gopīs , He is nevertheless present everywhere, even within the atoms of this universe ( aṇḍāntarastha-paramāṇu-cayāntarastham ). This is the verdict of the Vedic literature.
Unfortunately, the Māyāvāda philosophy, misguiding people by claiming the living entity to be the Lord, has created havoc throughout the entire world and led almost everyone to godlessness. By thus covering the glories of the Supreme Lord, the Māyāvādī philosophers have done the greatest disservice to human society. It is to counteract these most abominable activities of the Māyāvādī philosophers that Lord Caitanya has introduced the Hare Kṛṣṇa  mahā-mantra .
harer nāma harer nāma harer nāmaiva kevalam 
    kalau nāsty eva nāsty eva nāsty eva gatir anyathā
“In this age of quarrel and hypocrisy the only means of deliverance is chanting the holy name of the Lord. There is no other way. There is no other way. There is no other way.” People should simply engage in the chanting of the Hare Kṛṣṇa  mahā-mantra , for thus they will gradually come to understand that they are not the Supreme Personality of Godhead, as they have been taught by the Māyāvādī philosophers, but are eternal servants of the Lord. As soon as one engages himself in the transcendental service of the Lord, he becomes free.
māṁ ca yo 'vyabhicāreṇa 
    bhakti-yogena sevate 
    sa guṇān samatītyaitān 
    brahma-bhūyāya kalpate
“One who engages in full devotional service, who does not fall down in any circumstances, at once transcends the modes of material nature and thus comes to the level of Brahman.” (Bg. 14.26) Therefore the Hare Kṛṣṇa movement or Kṛṣṇa consciousness movement is the only light for the foolish living entities who think either that there is no God or that if God exists He is formless and they themselves are also God. These misconceptions are very dangerous, and the only way to counteract them is to spread the Hare Kṛṣṇa movement.
