Prasad Krishnan - "The notion of a "Old man in the sky" is the "God" that is being denied here. This is the God of Abrahamic religions. "Rama" cannot be straightjacketed in the same category as Jesus or Allah. The Hindu conception of Ishwara is both as the antaryaami and the sarvavyaapi. It is incorrect to reject this Ishwara simply because one cannot "feel" His aid. According to the shaastra, the very inspiration to help oneself is got from Ishwara, who instigates all beings towards Dharma from within."
"Ishwara is also the karmaphaladaata, the one who bestows the fruits of karma. Karma as a dead law cannot function of its own accord. Moreover, without Ishwara in mind, performance of any actions creates only more bondage/confusion/samsaara. Thus one cannot escape Ishwara or deny His presence simply by the logic that "No other person is there to help me when I am in trouble". What is is Ishwara, this is the message of Vedanta. This message is enshrined in all practices in Hinduism. One merely has to bring this vision into all the ritualistic portions, and then they all become very much alive and necessarily helpful in the spiritual pursuit which one alone can undertake for oneself."
We can go still deeper and see karma itself as interaction with the Lord and all fruits of karma as evidence of the Lord's presence. Vedanta is revealed in a number of layers, one has to go deeper and deeper to answer all questions. It all comes to an end at the 'essence' I have mentioned above.
