यस्य संस्थे न वृण्वते हरी समत्सु शत्रवः ।
तस्मा इन्द्राय गायत ॥ ४ ॥

Yasya samsthe na vrunvate hari samatsu shatravah |
Tasma indraya gayata || 4 ||

Meaning:

यस्य (Yasya) – Of whom, whose. Here, “Yasya” refers to the person who lives under the protection of God. That is, one who has accepted God into the heart.

संस्थे (Samsthe) – Established, abiding, firmly dwelling within. It signifies that God is not merely remembered occasionally, but has become firmly established in the human heart. This is the deep state of meditation and devotion.

न (Na) – Not, no. It emphasizes that negative forces such as lust, anger, and similar tendencies cannot function there.

वृण्वते (Vrunvate) – Choose, approach, attack. It refers to the negative forces that attempt to attack and take control of the mind—desire, anger, jealousy, and all such inner disturbances.

हरी (Hari) – Here, “Hari” refers to the senses (such as the eyes, ears, and other sense organs) or to the power that drives them. The human senses are the means by which worldly desires attract the mind. When they remain uncontrolled, the mind falls into decline.

समत्सु (Samatsu) – In battles, in spiritual struggles. This does not refer to an external war, but to the battle that takes place within the mind—desire versus self-control, anger versus peace, ignorance versus wisdom. This inner conflict is what the Veda calls “Samatsu.”

शत्रवः (Shatravah) – Enemies. These are not external enemies, but the enemies within the mind: lust, anger, greed, ego, and jealousy. These are the forces that destroy a person from within.

तस्मै (Tasmai) – Unto Him, unto that Supreme Lord. One should turn with gratitude toward the Supreme Reality that grants such protection.

इन्द्राय (Indraya) – Unto Indra (here, the Supreme Reality, the Highest Divine Power). Here, Indra is not merely a deity but the symbol of the Supreme Spiritual Power that conquers the mind. He is the Supreme Lord who controls and masters the mind.

गायत (Gayata) – Sing, praise. It is not enough merely to remember God; one should live by praising Him. The chanting of the Divine Name (Nama Sankirtana) is explained as a power that purifies the mind.

Explanation:

The Vedic mantras examine the inner struggles of human beings more deeply than their external lives. They clearly teach that a person’s real enemies are not the adversaries of the outer world, but the forces such as desire, anger, and ego that arise within the heart. This mantra also expresses the same spiritual truth in a brief yet profound manner. Its central teaching is that when God becomes firmly established within the human heart, all the inner enemies are destroyed.

The first word of this mantra, यस्य (Yasya), means “of whom” or “whose.” Here, it refers to the person who has accepted God into the heart. In other words, devotion is not merely an external ritual; it is the state in which God becomes firmly established in the depths of one’s heart. True spiritual life begins not by seeking God outside, but by establishing Him within oneself.

संस्थे (Samsthe) means “to dwell firmly” or “to become permanently established.” God is not One who is remembered once and then forgotten; He must become a constant presence in the human heart. This is the highest state of meditation and devotion. When God becomes firmly established in the mind, that mind is naturally purified, and its thoughts are elevated.

न (Na) is the word of negation. Through this, the mantra declares that there is no place for negative forces where God abides. When the remembrance of God becomes firmly established in the human mind, destructive forces such as lust, anger, and greed can no longer enter it.

वृण्वते (Vrunvate) means “to attack,” “to approach,” or “to attempt to overpower.” It refers to the negative forces that seek to take control of the human mind. Desire, anger, jealousy, ego, and similar tendencies work as destructive powers from within. However, they cannot enter a mind that is firmly established in the remembrance of God.

हरी (Hari) here refers to the senses and the power that drives them. The eyes, ears, tongue, and the other sense organs are the channels through which the mind is drawn toward the external world. When these senses function without control, the mind becomes scattered and falls into decline. But the remembrance of God becomes the power that disciplines and governs the senses.

समत्सु (Samatsu) refers to spiritual battles. It is not an external war, but the struggle that takes place every day within the human heart. The conflict between desire and self-control, anger and peace, ignorance and wisdom—this is the real battle. In this inner struggle, a person must conquer oneself.

शत्रवः (Shatravah) refers to enemies. Here, it does not mean external enemies, but the enemies within the human heart. Lust, anger, greed, ego, and jealousy are the forces that destroy a person from within. The Veda declares these to be the true enemies.

In the second part of the mantra, the words तस्मै (Tasmai) and इन्द्राय (Indraya) appear. तस्मै (Tasmai) signifies that one should turn with gratitude toward the Supreme Reality that grants such protection. Although इन्द्राय (Indraya) refers to Indra, here it truly symbolizes the Supreme Divine Power that conquers and governs the mind. The Supreme Lord who controls, purifies, and elevates the human mind is referred to here as Indra.

गायत (Gayata) means “Sing” or “Praise.” It teaches that it is not enough merely to remember God; one should live by praising Him. Nama Smarana and devotional praise become powerful means of purifying the human mind.

The combined meaning of this mantra is that the person in whose heart God is firmly established cannot be overcome by inner enemies such as desire and anger. His heart becomes a protected divine fortress. Therefore, remembering and praising that Supreme Lord is the path to inner victory.

Finally, this mantra reveals one of the greatest truths of human life. It is not the external world that destroys a person, but the negative emotions that arise within. However, when God becomes firmly established in the heart, those enemies disappear naturally. Therefore, the remembrance of God is the highest protection and the true foundation of inner victory.

Conclusion:

The essence of this mantra reveals a profound truth about the inner life of a human being. It clearly teaches that a person’s real downfall is not caused by external enemies, but by the negative forces that arise within the mind, such as lust, anger, greed, and ego. However, when the mind becomes filled with the remembrance of God and He becomes firmly established within it, there is no place left for those negative forces. This is the central teaching of this mantra.

The establishment of God within the mind is not merely a thought or an idea; it is a spiritual transformation that brings the senses under control, focuses the mind, and directs life toward a higher purpose. Such remembrance of God becomes a source of protection in the inner battle of human life, destroying every force that seeks to pull a person downward. As a result, the mind attains peace, the intellect becomes clear, and life gains order and harmony.

This mantra further teaches that merely remembering God is not sufficient; by praising Him and embracing His Divine Name with heartfelt devotion in daily life, the mind becomes even more purified. Then a person gains the strength to conquer the senses and attains an inner stability that remains unmoved by the changing circumstances of the external world.

Finally, this mantra teaches that the true protection of human life is not found outside, but within the heart. When God becomes firmly established within, all the inner enemies are destroyed, and the individual attains a higher spiritual state filled with peace, victory, and inner fulfillment. This is the complete essence of this mantra.
