One who searches after real happiness—ramante yogina anante—unlimited happiness, he is intelligence. One who is satisfied with temporary happiness, he's not intelligent. Antavat tu phalaṁ teṣāṁ tad bhavaty alpa-medhasām (BG 7.23). Those who are satisfied with temporary happiness, they're not very intelligent. Tad bhavaty alpa-medhasām. Alpa-medha means those who have got little brain, they are satisfied with temporary happiness, and those who are advanced, yogīs, they are not satisfied with temporary happiness. They must be seeking for unlimited happiness. That can be achieved when you go back to home, back to Kṛṣṇa. Kṛṣṇa is eternal; His pastimes are eternal. Just join His pastimes: His rasa dance, His play with cowherds boy, His dealing with His father and mother in Vṛndāvana.
So our this movement is to join Kṛṣṇa's pastime. Tyaktvā dehaṁ punar janma..., punar janma naiti mām eti kaunteya (BG 4.9). Simply if you try to understand Kṛṣṇa... That is not very difficult. Everything is explained in the Bhagavad-gītā, what is Kṛṣṇa, and further explained in the Śrīmad-Bhāgavatam. So if you simply read our books, follow the rules and regulation, chant sixteen rounds, it will be not very difficult. Sevonmukhe hi jihvādau svayam eva sphuraty adaḥ (Brs. 1.2.234). Things will reveal to you.
So if you, in this life, simply try to understand Kṛṣṇa, then your life is successful. What is that success? Tyaktvā dehaṁ punar janma naiti (BG 4.9). After giving up this material body, no more acceptance of material body; we remain in our spiritual body. We have got our spiritual body. That is now covered by this material dress, subtle dress and gross dress. So if we give up the propensity of material sense gratification, that is mukti. So long we'll have a pinch, a drop of desire to enjoy material happiness, we'll have to accept a body, different types of body, out of the 8,400,000. But if we become satisfied with service of Kṛṣṇa, then we are no more interested with this material happiness. That is mukti. When we shall be detestful with this material happiness... Āra nāre bapa
Just like Jagāi-Mādhāi said, āra nāre bapa. No more (indistinct), ruination. That is mukti. Kṛṣṇa will give you all facility. He's giving facilities, whatever you want. Ye yathā māṁ prapadyante tāṁs tathaiva bhajāmy a... (BG 4.11). Therefore we see varieties of life. It is arranged by Kṛṣṇa through the agency of material potency. Prakṛteḥ kriyamāṇāni guṇaiḥ karmāṇi sarvaśaḥ (BG 3.27). It is going on. But if we say, "Kṛṣṇa...," to Kṛṣṇa, "Now, from this day, I surrender unto You. My Lord, I don't want anything material," then you are mukta, liberated. And if you keep the standard, māyā will not touch you. Then after giving up this body, you go back to home, back to Godhead. It is very easy.
So try to understand and be happy. Continue this Kṛṣṇa consciousness movement in right earnest. Kṛṣṇa will help you. Teṣāṁ satata-yuktānāṁ bhajatāṁ prīti-pūrvakam dadāmi buddhi-yogaṁ tam (BG 10.10). Anyone who's engaged with heart and soul in the service of the Lord, Kṛṣṇa is within everyone, He'll give you intelligence: "Do like this. Do like this." Yena mām upayānti. He gives such intelligence by which you can go back to Him again.
