With this shloka, Shri Krishna concludes the topic of sense restraint. Let us summarize the main points of this topic.

The senses have the power to destabilize the mind, and consequently, destroy the intellect’s capability to make proper judgements. The best way to control the senses is to practice one’s svadharma with devotion to a higher ideal. If we don’t, then even a stray thought about a material object will escalate into a chain of events that will bring about our downfall.

Changing the quality and direction of thoughts towards a higher ideal will result in a tranquil psyche, enabling us to move in the world of material objects without attachment or revulsion. And ultimately, this will result in peace and happiness.

A pictorial description of this topic was provided in the form of a rudderless ship at sea, that is blown here and there by wind. The wind represents the senses, the ship our mind, and the direction, our wisdom.

In the next shloka, Shri Krishna begins to conclude the second chapter of the Gita.
