The preach to be in 'Now' or 'Present', and that 'there is no past and no future' as given to public is highly misleading. This is Trans-Phenomenal instruction and not for this Phenomenal World. This is for those who have elevated themselves from the rest.
Here in this world we learn from past what to do and how to behave if such and such event takes place and plan for future to prevent mishappenings.
If the Principle of being in Now is applied to this worldly affair, there is a danger of misinterpretation and of becoming of people utterly selfish, not to bother even for coming generations as it might be interpreted as ruling that out...this is what most of our politicians and rulers do.
