Vishnupurana 3.12.p4

3.12.p4

"The wise should not read the Vedas on the Parva days, on impure seasons, upon untimetely thunder and the occurrence of eclipses. The attainment of heaven is a trifling thing to him who allays the anger of the angry, who is friend to all and freed from malice, and who removes the fear of the pious. A man should use an umbrella to protect him against the sun and rain; he should carry a rod when he goes by night or through a forest and he should use shoes if he wishes to save his body from being hurt. As he proceeds he should not look up nor about him, nor afar off but keep his eyes upon the ground to the extent of a couple of yards.
