Poison slayeth but one person, and a weapon also but one; wicked counsels, however, destroy an entire kingdom with king and subject. Alone one should not partake of any savoury viand, nor alone reflect on concerns of profit, nor alone go upon a journey, nor alone remain awake among sleeping companions. That Being who is One without a second, and whom, O king, thou hast not been able to comprehend, is Truth’s self, and the Way to heaven, even like a boat in the ocean.

In plain words: Poison or a weapon kills one person, but bad advice can ruin a whole nation. Don't eat tasty food alone, plan money matters alone, travel alone, or stay awake alone while others sleep. The One supreme Being, whom the king has not understood, is Truth itself and the way to heaven, like a boat across the ocean.
