You said that we should not think that whatever is happening is happening by the will of God, then why did Lord Sri Krishna tell Sri Aurobindo in Alipore Jail that whatever a man may think or do, he cannot do anything except helping my purpose. So Lord Sri Krishna told Arjun in the Gita that I am situated in the heart of all living beings and I am deceiving everyone with my Maya and making them act according to my will🤔

हां किन्तु अविद्या रूपी अंधकार के पीछे से। The Divine works from behind the veil of Yogamaya because of which the original Will gets distorted. Otherwise, the logical conclusion would be that all the evil and cruel deeds are done by the Divine and there would be no need of yoga and sadhana, etc. 

What Sri Krishna revealed to Sri Aurobindo in the Alipore Jail is that whatever men may do or say, how much ever they may oppose and resist the Divine Will, still it will fulfil itself in the end.

Original question in Hindi: आपने कहा कि हमें यह नहीं सोचना चाहिए कि जो भी कुछ हो रहा है वह भगवानकी इच्छा से हो रहा है फिर अलीपुर जेल में भगवान श्री कृष्ण ने श्री अरविंद को यह क्यों कहा कि कि मनुष्य चाहे जो कुछ सोचे या करें पर वह मेरे हेतु की सहायता के अतिरिक्त और कुछ नहीं कर सकते। तो भगवान श्री कृष्ण ने अर्जुन को गीता में यह कहा कि मैं सभी भूत प्राणियों के हृदय में स्थित होकर अपनी माया से सबको भरमा रहा हूं और अपनी इच्छा से चला रहा हूं।
