Srila Prabhupada – Anxiety . . . even in Vṛndāvana there is anxiety. Rādhārāṇī is in anxiety that “Kṛṣṇa is not here. How Kṛṣṇa will come?” The gopīs are also in anxiety. gopīs are so in anxiety that about them it is said that when Kṛṣṇa used to go to the forest for tending the cows, so gopīs were thinking at home that “Kṛṣṇa’s feet is so soft that we hesitate to take His feet on our breast, but He is now walking in the forest, and there were so many stones and pricks, and they are giving pain to the Kṛṣṇa’s lotus feet.” And thinking like this, they fainted. This is gopī. Kṛṣṇa is out of the village, and they are at home, and they are thinking of Kṛṣṇa and they fainted. This is also anxiety,  so much anxiety that fainted. But that is for Kṛṣṇa. Therefore gopīs are exalted. 

Ramya kecid upāsanā vraja-vadhu-varga vīrya kalpita. Śrī Caitanya Mahāprabhu, He recommends, “There is no better type of worshiping Kṛṣṇa than it was planned by the gopīs.” 

So there is also anxiety. So anxiety is spiritual anxiety and material anxiety. *Spiritual anxiety means you are advancing in spiritual life, and material anxiety means you are going downhill* .
