We all need to serve our Sadguru if we aim at realizing God in the present lifetime. One form of service is rendered by staying physically close to him which requires special prudence of not letting our personal emotions constrict the real spirit of service. Another way is to 'sincerely' seek 'his real happiness' through 'our selfless actions' which may or may not be performed in close proximity. The grace of spiritual master has the capacity to surpass the time and space if we have humbly submitted to him.
