In plain words
Rāma says to Lakṣmaṇa, ‘Lakṣmaṇa, did you hear Hanumān's words? His words show the humility and obedience of the Ṛg Veda. They bring out the retentive power of the Yajur Veda. They display the wisdom of the Sāma Veda. Listening to his words, one can tell he is master of all the śāstras. Hanumān is one who has fully grasped the four Vedas. Such a one alone is a true devotee. That a devotee of such holy conduct is Sugrīva's minister is Sugrīva's good fortune. For man, mind, word and deed must be one.
When mind, word and deed are one in a man, he becomes a man of truth, in the proper way; the man of truth, in the presence of God, ever attains, and ever gains Prema.
Only because he could recognise such grace, such attraction, such divinity could Hanumān become a devotee close to Rāma.
Even after the rainy season had passed, Sugrīva made no preparations for the search for Sītā, so Lakṣmaṇa went and spoke to him in anger and hurt his feelings. Sugrīva! You are an ingrate who has forgotten the help you received. You are a great villain who breaks his given word. Such fools, such ingrates, one must never forgive. Even for the sin of killing a brāhmaṇa there is atonement. Even for one who drinks liquor there is atonement. For the cruel one who forgets the good done to him, for the fool who breaks his given word, there is no atonement at all. If such people were cut to pieces and thrown away, even the crows and dogs would not touch them. Sugrīva, through whom did you get the position you enjoy today? What state were you in before? The moment you gained pleasures and riches, you forgot your word. A fool like you is not fit to rule at all. As Lakṣmaṇa was reviling him in this way, Tārā, the queen mother, and Hanumān came running, took hold of Rāma's hands and begged Him to forgive. ‘Lakṣmaṇa! Through Ajñāna, through delusion, through the vāsanās of the senses, Sugrīva is being bound to the world. As a rule, amid pleasures and comforts people do not recognise any Satya or Dharma. Only in hard times do they try to recognise and practise morality, honesty and Dharma. They remain in a state where they do not recognise what humanness is.
