Discrimination about the right or wrong food is for beginners in spiritual life. Those whose minds are absorbed in God are not affected by anything. The main thing is to fix the mind on Him…Try to focus your whole mind on God, and everything else will come afterwards. All rules, regulations, and spiritual practices are meant for God-realization. All these mechanical rules and routines are meaningless if one’s mind is not focused on God. In whatever circumstances we find ourselves, if we can live a God-centred life, no miseries can touch us. Even in the great calamities of life if one can feel God’s presence in the heart one experiences infinite joy. So we need Him. Once we attain Him, we have everything; we require nothing else.
