Every living being desires the topmost level of enjoyment in this material world, and yet everyone is unhappy here. This unhappiness is present on all the higher planets, despite a longer life span, higher standards of enjoyment and comfort. That is due to the law of material nature. We can increase the duration of life and standard to the highest capacity, and yet by the law of material nature we will be unhappy. The reason for this is that the quality of happiness which is suitable for our constitution is different from the happiness which is derived from material activities. The living entity is a minute particle of the superior spiritual energy of the Lord, which is sac-cid-ānanda-vigraha [Bs. 5.1], and therefore he has the necessary propensity for joy which is spiritual in quality. Unfortunately for him, he is trying vainly to attain his enjoyment from the foreign atmosphere of material nature.
A fish that is taken out of the water cannot be happy by any arrangement on land. He must be supplied with water. In the same way, the minute sac-cid-ānanda living entity cannot be really happy through any amount of planning conceived by his illusioned brain in this material universe. He must therefore be given a different type of happiness which is spiritual in essence. Our ambition should be aimed at enjoying spiritual bliss and not this temporary happiness. Some philosophers claim that spiritual bliss is attained by negating material happiness and material existence. Theoretical negation of material activities as propounded by Śrīpāda Śaṅkarācārya may be effective for an insignificant section of mankind, but the best and surest way for everyone to attain spiritual bliss was propounded by Lord Śrī Caitanya Mahāprabhu by means of devotional activities. These devotional activities can change the very face of material nature.
Hankering after material happiness is called lust, and lusty activities are sure to meet with frustration in the long run. The body of a snake is very cool, but if a man, wanting to enjoy this coolness, garlands himself with a venomous snake, he will surely be killed by the snake’s venomous bite. The material senses are compared to snakes; indulgence in material happiness will surely kill our spiritual identity. Therefore a sane man should be ambitious to find the real source of happiness.
In order to find this source, however, we need some knowledge of what that happiness is. There is the story of the foolish man who had no experience with sugar cane. When he asked his friend about the characteristics of sugar cane, he was imperfectly informed that sugar cane resembles the shape of a bamboo stick. Consequently he began trying to extract juice from bamboo sticks, but naturally he was baffled in his attempts. This is the situation with the illusioned living entity who, in his search for eternal happiness, ties to extract happiness from this material world, which is not only full of miseries but is also transient and flickering. In Bhagavad-gītā the material world is described as being full of miseries.
ābrahma-bhuvanāl lokāḥ
punar āvartino ’rjuna
mām upetya tu kaunteya
punar janma na vidyate
punar āvartino ’rjuna
mām upetya tu kaunteya
punar janma na vidyate
“From the highest planet in the material world, down to the lowest, all are places of misery, where repeated birth and death take place. But one who attains to My abode, O son of Kuntī, never takes birth again.” (Bg. 8.16)
The ambition for happiness is natural and good, but the attempt to derive it from inert matter by so-called scientific arrangements is an illusory attempt doomed to frustration. Those who are befooled cannot understand this. How a person is driven by the lust for material happiness is also described in Bhagavad-gītā.
idam adya mayā labdham
imaṁ prāpsye manoratham
idam astīdam api me
bhaviṣyati punar dhanam
imaṁ prāpsye manoratham
idam astīdam api me
bhaviṣyati punar dhanam
“The demoniac person thinks: ‘So much wealth do I have today, and I will gain more according to my schemes. So much is mine now, and it will increase in the future, more and more.’ ” (Bg. 16.13)
This atheistic or godless civilization is a huge affair contrived for the gratification of our senses, and now we are all mad after money in order to maintain this empty shell. Money is sought after by everyone because that is the medium of exchange for objects for sense gratification. Obviously the expectation of peace in such an atmosphere of gold rush pandemonium is a utopian dream. As long as there is the slightest tinge of sense gratification or desire for sense gratification, peace will remain far, far away. This is because by nature we are all eternal servants of the Supreme Lord and therefore cannot enjoy anything for our personal interests. It is therefore necessary for us to learn how to employ our senses in the transcendental service of the Lord, and to utilize everything to serve His interest. This alone can bring about much desired peace. A part of the body cannot in itself be independently happy. It can only derive its happiness and pleasure out of serving the entire body. The Supreme Lord is the whole, and we are the parts, but we are all busily engaged in activities of self-interest. No one is prepared to serve the Lord. This is the basic cause for our conditioning in material existence and for our resultant unhappiness.
