77. ‘Just, Vāseṭṭha, as a mighty trumpeter makes himself heard—and that without difficulty—in all the four directions; even so of all things that have shape or life, there is not one that he passes by or leaves aside, but regards them all with mind set free, and deep-felt love.’
‘Verily this, Vāseṭṭha, is the way to a state of union with Brahmā.’
78. ‘And he lets his mind pervade one quarter of the world with thoughts of pity, sympathy, equanimity, and so the second, and so the third, and so the fourth. And thus the whole wide world, above, below, around, and everywhere, does he continue to pervade with heart of pity,... sympathy,... equanimity, far-reaching, grown great, and beyond measure.’
79. ‘Just, Vāseṭṭha, as a mighty trumpeter makes himself heard—and that without difficulty—in all the four directions; even so of all things that have shape or life, there is not one that he passes by or leaves aside, but regards them all with mind set free, and deep-felt pity, sympathy, equanimity.’
‘Verily this, Vāseṭṭha, is the way to a state of union with Brahmā.’
80. ‘Now what think you, Vāseṭṭha, will the Bhikkhu who lives thus be in possession of women and of wealth, or will he not?’
‘He will not, Gotama!’
‘Will he be full of anger, or free from anger?’
‘He will be free from anger, Gotama!’
‘Will his mind be full of malice, or free from malice?’
‘Free from malice, Gotama!’
‘Will his mind be tarnished, or pure?’
‘It will be pure, Gotama!’
