Śrīmad-Bhāgavatam · Text 6.14.17
Who is speaking and story frame
अङ्गिरा उवाच
अपि तेऽनामयं स्वस्ति प्रकृतीनां तथात्मन: ।
यथा प्रकृतिभिर्गुप्त: पुमान् राजा च सप्तभि: ॥ १७ ॥
aṅgirā uvāca
api te ’nāmayaṁ svasti
prakṛtīnāṁ tathātmanaḥ
yathā prakṛtibhir guptaḥ
pumān rājā ca saptabhiḥ
The great sage Aṅgirā said: My dear King, I hope that your body and mind and your royal associates and paraphernalia are well. When the seven properties of material nature [the total material energy, the ego and the five objects of sense gratification] are in proper order, the living entity within the material elements is happy. Without these seven elements one cannot exist. Similarly, a king is always protected by seven elements — his instructor (svāmī or guru), his ministers, his kingdom, his fort, his treasury, his royal order and his friends.
