Mr Singh...Very well written, but I must mention this, you were a victim here who trusted your guru... It's a perfect time to mention this saying by buddha "You don't need to a guru to be know about self-realization. A so called guru/saint is all human and his views/opinions could also be wrong. Self realization is something which must be attained by your own self, not by seeking a guru". Once you've reach a stage you will be able to realise the person who knows most. Then you will be able to follow him.
Please remember, to attain spiritual bliss you need to find answers to your questions of your own. A guru is one who just shows the path.
Buddha, vivekanandha, ramakrishna, adi shankara, ramana etc...became great people cos they sought the answers of their own. Learnt them from nature. The human mind has all the answers. We just need to self-introspect ourselves...
