Dear Sir,
Spirituality leads to renunciation. Science leads to indulgence. Hence both are contradictory. When you talk of "Spirituality starts where science ends", what it means is not singularity, but "renunciation starts where indulgence ends". Since end of indulgence is gradual with increase of renunciation, one can give up science as one moves towards spirituality. You must remember that science is "vignyaanam" - "vishishta gnyaanam" and not "gnyaanam". The word "vishishta" points to its special characteristic, which attracts towards worldly objects. At best you can equate singularity with "moksha" - the ultimate liberation, not spirituality.
If you read our comments below the Essays of Mr. B.N. Sreenath, and Mr. Peter A Jackson, you will realize that we are using many terms found in the Vedas. This shows that we are familiar with the Vedas, Braahmanas, Aaranyakas and Upanishads. We know that all translations available as on date are wrong. Hence we dot blame you, because you are following wrong descriptions. We only tried to prevent you from bringing it to international scientific community, because while in our country we ignore these, there is a great demand for these books abroad. In fact one publisher told us that there is so much demand that he is unable to meet the export orders. The people abroad - many of them - will see the fallacy or be misguided like the development of string theory from the Upanishad dictum of "tat sootram", which has been wrongly interpreted. It actually referred to the three fold structure of atoms - the center of mass with the nucleus, the orbits and the energy that binds these two. Without this energy, no particle will be stable. Hence sootra vaayu has been given due importance. However, this has been misunderstood in QM.
If you want to progress in spirituality, you must renounce not only science, but the world also, which includes love. Because love implies duality of the lover and the loved. Thus, it creates bondage. At the adwait stage, there is no duality - hence no love also.
