“The powers of the mind should be concentrated and the mind turned back upon itself; as the darkest places reveal their secrets before the penetrating rays of the sun, so will the concentrated mind penetrate its own innermost secrets.” ShouldMindSecretSunRaysPenetratePower Of The Mind Author:Swami Vivekananda
“It should be the aim of grand strategy to discover and pierce the Achilles' heel of the opposing government's power to make war. Strategy, in turn, should seek to penetrate a joint in the harness of the opposing forces. To apply one's strength where the opponent is strong weakens oneself disproportionately to the effect attained. To strike with strong effect, one must strike at weakness.” ShouldWarGovernmentTurnsStrongForceEffectsMilitaryWeaknessAimStrategyOneselfStrikesOpponentsHeelsJointsPenetrateOpposingPierceHarnessAchillesWar StrategyAchilles Heel Author:B.
