In plain words
The happiness that arises in enjoyment is Viṣayānanda; the happiness of deep sleep is Brahmānanda; the lingering sweetness on waking is Vāsanānanda. Love of the Self is Ātmānanda, the joy of samādhi is Mukhyānanda, the peace of neutrality is Nijānanda, contemplation of the One is Advaitānanda, and the joy born of the great teaching is Jñānānanda.
