Valmiki Ramayana Ayodhya Kanda Sarga 30 Shloka 18

त्वया सह in your company, यः that which is obtained, सः that alone, स्वर्गः is heaven, त्वया विना without you, निरयः is hell, इति thus, जानन् while being aware, राम Rama, मया सह along with me, पराम् great, प्रीतिम् pleasure, गच्छ obtain.

Wherever I be with you is heaven and without, hell. O Rama, recognise this truth, and derive great pleasure in my company.
