Peace and joy are derived by man from within his heart. They are not at all related to physical comforts. It is impossible to attain true peace and joy by a man of this world unless a perfect balance is attained within and without.

Maharishi Aurobindo has clearly stated,

• "People of the west have taken physical life to its zenith, now India’s role starts. It has to bring all these under the command of spiritual power and establish heaven on earth."
  

• Whatever our religious teachers may proclaim before the world but the truth is that the extent of darkness that is present in the spiritual world of India today was never there before.

In this regard, Shri Maa says,

• "The problems of the entire world have got concentrated in India. Once these are resolved, the burden of the world will lighten."
  

• It is a bitter truth that at present India has the maximum ‘Tamas’ as compared to the rest of the world. Some people might feel very sad to know this but I am very happy. Everything changes its form after crossing a particular limit.

• We know that whenever the demonic forces have dominated this land, God has descended in the form of Rama and Krishna to kill them and have lightened the burden of the earth.

Bhagwan Shri Krishna has clearly stated in the Bhagwat Geeta

yadā yadā hi dharmasya glānir bhavati bhārata
abhyutthānam adharmasya tadātmānaṁ sṛijāmyaham (4:7)

paritrāṇāya sādhūnāṁ vināśhāya cha duṣhkṛitām
dharma-sansthāpanārthāya sambhavāmi yuge yuge (4:8)

- Bhagwan Shri Krishna

(Bhagwad Geeta)

Whenever there is a decline in righteousness and an increase in unrighteousness, O Arjun, at that time I manifest Myself on earth. To protect the righteous, to annihilate the wicked, and to re-establish the principles of dharma I appear on this earth, age after age.

Maharishi Aurobindo said,

• "On 24 November 1926, Shri Krishna descended into the physical. Shri Krishna is not the supramental light. The descent of Shri Krishna would mean the descent of the Overmind Godhead, preparing, though not itself actually, the descent of Supermind and ANANDA. Krishna is ‘Anandmaya’. He supports the evolution through the Overmind leading it towards the Ananda."

  This is completely true.

In the Alipore Jail, Bhagwan Shri Krishna had told Maharishi Aurobindo,

• "I am raising this country to spread my message. This message is about the message of that ‘Sanatan Dharm’ about which you didn’t know till now but now you know it. When you go out of the prison, tell your countrymen that they are being raised for ‘Sanatan Dharm’, they are not being raised for achieving their selfish motives but for the sake of the world.
  When it is said that India is great, it means that ‘Sanatan Dharm’ is great. I have shown you that I am everywhere and within everyone. I am present not only in those who are fighting for the nation but also in those who are opposing it. Knowingly or unknowingly, whatever men may think or do, they can do nothing but help in my purpose. It is my ‘Shakti’ (power) that is working and that day is not far off when success will be attained."

The above description matches with what Shri Krishna said in the Bhagwat Geeta -

• īśhvaraḥ sarva-bhūtānāṁ hṛid-deśhe ‘rjuna tiṣhṭhati
  bhrāmayan sarva-bhūtāni yantrārūḍhāni māyayā (18:61)

  The Supreme Lord dwells in the hearts of all living beings, O Arjun. According to their karmas, He directs the wanderings of the souls, who are seated on a machine made of material energy.

• All the saints of the world have unanimously made a prediction that the Supreme Power will descend in the human form in the Northern part of India. Everyone is of the view that with its gradual development, it will reveal itself before the world by the end of the century and take control of it. According to my direct experience, that Supreme Power will spread its light all over India by 1993.

• By the end of the century, it will take all the physical powers under its control and start managing them. In this way, Kali-Yuga will come to an end and only the ‘Sattvik’ powers will rule the world. In this way, when the spiritual power will start ruling over the physical power, the era will change and heaven will descend on earth. Whatever is about to happen, can be sensed by the predictions of the saints of the world.
