Text 9]
The Supreme Lord Is Equal to Everyone
13
TRANSLATION
The all-pervading Personality of Godhead exists within the heart of every living being, and an expert thinker can perceive how He is present there to a large or small extent. Just as one can understand the supply of fire in wood, the water in a waterpot, or the sky within a pot, one can understand whether a living entity is a demon or a demigod by understanding that living entity's devotional performances. A thoughtful man can understand how much a person is favored by the Supreme Lord by seeing his actions.
PURPORT
In  Bhagavad-gītā  (10.41) the Lord says:
yad yad vibhūtimat sattvaṁ śrīmad ūrjitam eva vā tat tad evāvagaccha tvaṁ mama tejo-'ṁśa-sambhavam
“Know that all beautiful, glorious and mighty creations spring from but a spark of My splendor.” We have the practical experience of seeing that one person is able to do very wonderful things whereas another cannot do those same things and cannot even do things that require only a little common sense. Therefore, how much a devotee has been favored by the Supreme Personality of Godhead can be tested by the activities the devotee has performed. In  Bhagavad-gītā  (10.10) the Lord also says:
teṣāṁ satata-yuktānāṁ bhajatāṁ prīti-pūrvakam dadāmi buddhi-yogaṁ taṁ yena mām upayānti te
“To those who are constantly devoted and who worship Me with love, I give the understanding by which they can come to Me.” This is very practical. A teacher instructs the student if the student is capable of taking more and more instructions. Otherwise, in spite of being instructed by the teacher, the student cannot make strides in his understanding.
