Text 2.70.15

राजन्पितुर्गमिष्यामि सकाशं दूतचोदितः।
पुनरप्यहमेष्यामि यदा मे त्वं स्मरिष्यसि॥

rājan pitur gamiṣyāmi sakāśaṁ dūta-coditaḥ
punar apy aham eṣyāmi yadā me tvaṁ smariṣyasi

rājan = O king; pituḥ = My father; gamiṣyāmi = I have to go; sakāśam = to; dūta-coditaḥ = upon the request of these messengers; punaḥ api aham eṣyāmi = but I will return; yadā = when; me = Me; tvam = you; smariṣyasi = remember.

O king, I have to go to My father upon the request of these messengers but I will return when you remember Me.

“When you remember Me” means “when you think that I should come here.”
