If possible could someone provide me with references to sutras where the Buddha broaches such topics? In my previous question I asked about it generally and a kind user told me that information could be found in the second and third turnings of the Dharma wheel. Since I am fairly new to Buddhism, could you tell me where exactly to find answers to above question?
I will constrain my answer to the second turning of the wheel of dharma - which is held to be of definitive meaning while the first and third are said to be of interpretive meaning - and answer from Nagarjuna's seminal Fundamental Verses for explaining the Prajñāpāramitā the Buddha's teachings from the Second Turning of the Wheel of Dharma.

To put a very fine point on it, the topic is brought up again in the Chapter on Nirvana, page 529:
The pithy answer is that the Tathagata continues in the same essenceless existence after his passing away as he did before he passed away and this is similarly true of all sentient beings. We all exist free of essence.
Hope this is helpful!
