Bose had come to realize that Gandhi's doctrine of non-violence was not doing much in forcing the British to retreat. He went to Germany to seek Hitler's assistance in India's struggle for freedom.
Was Bose welcome in Germany? Did Hitler agree to support Bose's cause? Was there anything that Hitler really did to help Bose?
Yes, Bose was welcome in Germany. The Germans could have denied him entry if they wanted to, and so there are no doubts that they were happy to see him in their country. However, Hitler repeatedly refused to issue a declaration supporting India's independence, and this suggests that he personally did not support Bose's cause. It also has to be remembered that Hitler had written in Mein Kampf that he preferred to see India under the British than under any other country. Bose had asked Hitler to withdraw this in their meeting, but Hitler pointedly refused. Bose also openly attacked the invasion of Russia, and had called it an act of unprovoked aggression.
Thus, it can be concluded that the support that Bose received in Germany was due to the efforts of the Germany's foreign ministry and its intelligence wing, Abwehr. Hitler personally did not like or encourage Bose as a leader.
The biography of Adam von Trott A Good German by Giles MacDonogh has a chapter on Bose and his involvement with nazi Germany in the 1930s and 1940s.
Trott headed up the India Department within Germany's wartime Foreign Ministry and looked after Bose's 18-month stay in Germany during the war.
Bose had visited Germany in 1933 but Hitler refused to see him. Those senior nazis who would see him and wanted to cooperate (an arms shipment to Indian revolutionaries was promised) tended to be on the left wing of the party which was of course wiped out a year later in the Night of the Long Knives.
Hitler approved of British rule in India and said so in Mein Kampf "I would rather see India under British domination than under that of any other nation". And he scoffed at the idea of an Indian uprising. Before the war he suggested to Lord Halifax that the British have Bose shot.
Bose returned to Germany in April 1941. He pressed the Germans to sponsor an Indian government-in-exile and to help him recruit an Indian Army from prisoners taken in North Africa, but initially got only evasive answers. However Trott was allowed to make "generous amounts of money" available to Bose and his cronies. Bose set himself up in a palatial villa near Berlin. He was also allowed to set up a "Free India Centre" in the German capital. Towards the end of 1941 the Germans at last began to build up the "Indian Legion" that Bose had asked for 6 months earlier. The legion numbered a few thousand men but was dismissed by one of Trott's colleagues as "a piece of comic opera which no one took seriously".
But Bose never hit it off with senior nazis. His meetings with Ribbentrop were frosty. His one meeting with Hitler (May 1942) was "anything but cordial". Bose believed the meeting had been a failure and left for Japan towards the end of 1942.
Hitler supported Bose enough to send him to Japan on U-180 with 3 tons of Gold to raise an army from Indian POWs in Thai/Malay POW camps.
In return Hitler got an effective spy network in India codenamed Trompeta, which sent intelligence home via radio on German merchant vessels interned in the Harbour at Goa.

hitler was never interested in india..the foreign office was to some extent,the likes of ribbentrof and gobbels,the only Nazi serious and knowledgable about india was Himmler.Hitler belivede that Germany and Russia could have been friend in the ist war had Russia not recognized Poland as a free country.he didn't want to commit the same mistake wit britian.he belived there was every possibility of an agreement with britian and didn't want to screw it.moreover he was ok with british rule in india if the brits gave him an free hand in eastern Europe.
