All of us with one voice call one God differently as Parmatma, Ishwara, Shiva, Vishnu, Rama, Allah, Khuda, Dada-Hormuzda, Jehova, God and an infinite variety of names.
The earth, the air, the land and the water are not an inheritance from our fore fathers but on loan from our children. So we have to handover to them at least as it was handed over to us.
No sacrifice is worth the name unless it is a joy. Sacrifice and a long face go ill together. Sacrifice is 'making sacred'. He must be a poor specimen of humanity who is in need of sympathy for his sacrifice.
