So spiritual life means you have to control. That is called gosvāmī. One who has control over the senses, one who has control over eating, you'll find this instruction in the Nectar of Instruction: jihvā-vegam udaropastha-vegam manaso vegam etān vegān yo viṣaheta dhīraḥ pṛthivīṁ sa śiṣyāt (NOI 1). Guru should be . . . Guru means one who has control over the six duties, six engagements. Manaḥ, to control the urge of the mind. The mind wants to do this. "No, if it is not profitable, don't do this." The control over the mind. Control over the senses, control the words. I am angry, I want to abuse somebody with some ill names. "No, why shall I . . ." Control of the . . . Talking unnecessary, useless talking, that is control over the tongue. Vāco vegam. Krodha-vegam: "I am just going to be very angry upon you." No, we have to control. In this way, when one is able to control over these things, especially jihvā-vegam udaro-vegam upastha-vegam, straight line—the urge of the tongue, the urge of the belly and the urge of the genital—then we become svāmī, gosvāmī. Artificially, it is not . . . It is to be practised. Nidrāhāra-vegam, these are material things.
So to control over the material urges, that is required in spiritual life. We have to come to the spiritual platform. That is called tapasya. Tapo divyaṁ putrakā yena sattvaṁ yasmād brahma-saukhyaṁ tv anantam (SB 5.5.1). We are searching after happiness, but in the material world you cannot have happiness. That's a fact. Whatever little happiness you get, that is also distress. One has to attain to that stage of happiness with distress. So that is a long history; everyone knows that happiness is not possible. But we arrange to get so-called . . . Happiness means sense gratification. That is not happiness. Sukham ātyantikaṁ yat tad ātindriya grāhyam (BG 6.21). Directly sense perception is not happiness. These things are in the Bhagavad-gītā, you will find: sukham ātyantikaṁ yat tad atīndriyaṁ grāhyam. Ātindriyam means beyond these material senses, transcendental, there is another happiness. That is transcendental bliss. That we perceive little bit while we are chanting. By chanting, chanting, chanting, when you'll be purified, then you will have the opportunity of tasting that transcendental bliss. Otherwise, the so-called happiness derived from the senses, that is not happiness. That is crude; that is for the fools and rascals. That is not happiness.
So we should utilize our time very carefully. Puṁso varṣa-śatam . . . Because here is the calculation that although, supposing that I shall live for one hundred years, puṁso varṣa-śataṁ hy āyus tad-ardhaṁ cājitātmanaḥ (SB 7.6.6). Immediately, those who are not controlling the senses, ordinary, they are immediately at least half minus, fifty years gone for sleeping. And then niṣphalaṁ yad asau rātryāṁ śete andhaṁ prāpitas tamaḥ. So in this way, if you are actually serious . . . It is not that we are imposing something.
