Shiva Purana
ब्रह्मलोकप्रदं विद्यात्ततः पूजादिकं तथा । सिंधुनद्यां तथा स्नानं सिंहे कर्कटगे रवौ २१ ।
Knowledge leads to the attainment of Brahmaloka, and similarly, worship and other rituals. Bathing in the Sindhu river, as well as in the Ravi (sun), and at the places of Leo (siṃha) and Crab (karkata), also purifies.
