So yajñaiḥ saṅkīrtanaiḥ, you keep Śrī Caitanya Mahāprabhu and perform yajña, the saṅkīrtana-yajña, before Him, and you become all-perfect. So easy. So easy. Because you cannot give up yajña. But in this age, Kali-yuga, people are so unfortunate, so rubbish, that it is not possible to perform the Vedic ritualistic yajña. That is not possible. Therefore Kṛṣṇa has given you the opportunity that you can perform. Kalau tad dhari-kīrtanāt. Kṛte yad dhyāyato viṣṇuṁ tretāyāṁ yajato makhaiḥ (SB 12.3.52). Makha means yajña. That was being performed in the Tretā-yuga. And in the Satya-yuga, meditation. In the Dvāpara-yuga, Deity worship. Kalau tad dhari-kīrtanāt. In the Kali-yuga, simply by kīrtanād eva kṛṣṇasya (SB 12.3.51). And this is the śāstra's injunction.
So I am very pleased that you are keeping this center nicely in our own standard by performing yajña, by saṅkīrtana, and today is Rādhāṣṭamī. You perform. Our yajña is saṅkīrtana, and Śrīmatī Rādhārāṇī is the pleasure potency of Kṛṣṇa. Rādhā kṛṣṇa-praṇaya-vikṛtir hlādinī śaktir asmād ekātmānāv api deha-bhedaṁ gatau tau, śrī-caitanyākhyaṁ prakaṭam adhunā tad-dvayaṁ caikyam āptam (CC Adi 1.5). When Kṛṣṇa . . . Kṛṣṇa is one, ekam advitīyam. But eko bahu syāt, He can expand Himself. So when He wants to enjoy, so the pleasure potency is manifested from His personal body. That pleasure potency is Rādhārāṇī. Rādhārāṇī is not ordinary living entity. Rādhārāṇī is Kṛṣṇa's personal pleasure potency, hlādinī-śakti.
So just today is the appearance day of hlādinī-śakti. So if you want to please Kṛṣṇa . . . because our business is to please Kṛṣṇa. Hari-toṣaṇam. Our this movement is hari-toṣaṇam. Saṁsiddhir hari-toṣaṇam. Ataḥ pumbhir dvija-śreṣṭhā varṇāśrama-vibhāgaśaḥ. Varṇāśrama-vibhāgaśaḥ. Svanuṣṭhitasya dharmasya saṁsiddhir hari-toṣaṇam (SB 1.2.13). Not only our. This is the aim. In the Bhagavad-gītā it is also said, vedaiś ca sarvair aham eva vedyaḥ (BG 15.15). The whole Vedic literature is meant for searching out Kṛṣṇa and to satisfy. So Kṛṣṇa personally comes to give you the information. Sarva-dharmān parityajya mām ekaṁ śaraṇam (BG 18.66): "You rascal, you give up all these engagements. Simply you surrender unto Me."
And what about other demigods? There are so many demigods. What we have to do? Kāmais tais tair hṛta-jñānāḥ (BG 7.20): "This demigod is worshiped by persons who have lost all intelligence." Hṛta-jñāna. Hṛta-jñāna means naṣṭa-buddhayaḥ, one who has lost intelligence. There is no need. Simply mām ekam. That is the instruction of Bhagavad . . . that is the śāstra instruction. Viṣṇur ārādhyate panthā nānyat tat-toṣa-kāraṇam. Na te viduḥ svārtha-gatiṁ hi viṣṇum (SB 7.5.31). Oṁ tad viṣṇoḥ paramaṁ padaṁ sadā paśyanti (Ṛg Veda 1.22.20). This is Ṛg Veda mantra. Actual aim of life is to satisfy Lord Viṣṇu, and Kṛṣṇa is the origin of viṣṇu-tattva. And He is pleased through Rādhārāṇī. Therefore we don't keep Kṛṣṇa alone. No. Rādhā-Kṛṣṇa. First Rādhārāṇī.
