Srila Prabhupada says in his lecture on Srimati Radha Rani:
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 bhuvi purā deha-bhedaṁ gatau tau, śrī-caitanyākhyaṁ prakaṭam adhunā tad-dvayaṁ caikyam āptam [Cc. Ādi 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 of the 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. 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. So that day is today. First you have to worship Rādhārāṇī. If you go through Rādhārāṇī...
Therefore in Vṛndāvana you will see all devotees, they will address one another, "Jaya Rādhe." Still. Because they know that "If Rādhārāṇī is pleased, if I can please Rādhārāṇī..." Rādhārāṇī is presented, the original pleasure potency, always absorbed in thought of Kṛṣṇa. So anyone who comes before Rādhārāṇī to serve Kṛṣṇa, oh, She becomes so pleased, "Oh, here is a devotee of Kṛṣṇa." She immediately recommends, "Kṛṣṇa, oh, here is a devotee. He is better than Me." This is Rādhārāṇī. I may be a, not devotee. I may be most fallen rascal. But if I try to reach Kṛṣṇa through Rādhārāṇī, then my business is successful. Therefore we should worship Rādhārāṇī first. That is our business. Instead of offering directly one flower to Kṛṣṇa, you just put it in the hands of Rādhārāṇī: "My mother Rādhārāṇī, Jagan-mātā, if you kindly take this flower and offer it to Kṛṣṇa." "Oh," Rādhārāṇī says, "Oh, you have brought a flower?" Kṛṣṇa said, patraṁ puṣpaṁ phalaṁ toyaṁ yo me bhaktyā prayacchati [Bg. 9.26], but don't try to offer Kṛṣṇa directly. Just offer through Rādhārāṇī. It will be very much appreciated by Rādhārāṇī.
So this is our philosophy, to please Kṛṣṇa through Rādhārāṇī, and just today is the auspicious day of Rādhārāṇī appearance. So we should offer puṣpāñjali and pray to Rādhārāṇī that "Rādhārāṇī, kindly be merciful and tell about me to Your Kṛṣṇa. To Your Kṛṣṇa. Kṛṣṇa is Yours." Kṛṣṇa, Rādhā-Kṛṣṇa. Kṛṣṇa is not independent. Kṛṣṇa is Rādhārāṇī's property. So you have to approach Kṛṣṇa through Rādhārāṇī. That is, today is the auspicious day. Worship Rādhārāṇī very nicely and be happy.
Thank you very much. Hare Kṛṣṇa.
