Wine is good for both health and the spiritual life. It is an intoxicant and tonic for both. If after drinking wine, thoughts are diverted to spiritual advancement, it is a great push toward the Goal; otherwise, it can lead to hell. Wine is such that either it raises you to the highest pinnacle or makes you fall into the deepest ditch.
The main object of drinkers of old — in the ancient past — was spiritual. Seekers then used not only wine but also hemp, heroin, hashish and opium; so much so that even Sadgurus would indulge in them. Sai Baba used to smoke a chillum and Upasni Maharaj smoked beedies. But eventually during those times, ordinary people indulged in these intoxicants for the wrong reasons. They could not understand their proper use and the effects of the intoxication diverted their thoughts to carnal desires — worst of all to lust, the greatest obstacle in the Way.
